I regularly play at my local FNM, including all the pre-release events and recently a PPTQ (made top 8, my best ranking so far at anything other than FNM). As for actual stories though, my best memories are from Commander games. Just this friday, we had a 5 player game at my friends house. I'm running monoblue Thassa, the idea behind the deck is to use Thassa's unblockable ability to help a bunch of cheap creatures get through, and all of those creatures draw cards on dealing damage, whilst scrying into what I need, doubling my upkeeps with Paradox Haze and maintaining tempo with cheap bounce spells (especially recursive bounce spells like Reality Strobe, which combos beautifully with the Haze). Basically Thassa is the draw engine, which ultimately drives me into bigger and bigger spells, mostly involving stealing or copying other peoples permanents with things like Control Magic, Volition Reins, Gather Specimens, Corrupted Conscience, etc, and then using their own cards against them.
The other players are running Naya monsters, monored Jaya burn, Mogis demons and Selesnya overpowered bullshit. Guess who quickly became the major target. The selesnya guy had managed to get Iona out, naming red, effectively shutting down the other 3 players, and was slowly bashing in at me, the only person not locked down. Iona was proving difficult to kill, due to various lands that gave it regen and creatures that could tap to give stuff protection, but, after dropping to only 4 life, I managed to use Clever Impersonator to make a copy of his Avacyn, giving all of my permanents indestructable and now had an 8/8 flyer to defend with, and shortly thereafter, due to a group effort we ganged up on and killed Iona with about 5 different killspells on the stack until he ran out of responses, at which point everyone unloaded into him and finally took him down before he could get Elesh Norn or some other evil shit down. Then the Rakdos guy decided since he was nearly dead as well, to just blow up all the land, except mine which was indestructable. I was totally ok with that. Then myself and the Naya player teamed up, killed off the monored player and I promptly stabbed him in the back by killing his Gisela. He somehow managed to get enough land back out on the field to then immediately cast his OWN Iona, naming blue (as he cast it, not before it landed) and I Gathered Specimens in response, taking it away from him before it entered, at which point I could instead name green, making him scoop. It was then a simple matter to finish off the remaining player.
However, since Sunday, 1 addition has been made to this deck which now allows it to make a truly ludicrous play, which I pulled off no more than 20 minutes after putting it into the deck. The card in question is Palinchron. The game went like this;
It's me vs monored Jaya and Mogis again. My starting hand is terrible, even after mulligans. I am forced to discard merchant scroll early on. I could have played it, but decided at the time it wasn't worth it. It will be worth it later. So for the first half of the game I'm basically a non-issue, the other guys are making plays and trading blows, I get hit for like 22 somewhere in the cross fire, before I finally start getting land. I draw Palinchron. Then I draw High Tide. My infinite mana combo pieces are in hand, but I have no win-con. I do however, have Archeomancer and Rite of Replication, which might be fun if I see anything good from my opponents worth copying 5 times. I start acruing land, slowly building towards the point where I can use High Tide and then play Palinchron, untap my lands and then bounce Palinchron back to play it again and net infinite mana. Then Jaya guy blows up my Temple of the False God and for some reason I think I can still make the combo work next turn despite now being down 2 mana (I must have misscounted and thought I had enough). I play High Tide, making all my islands tap for an additional blue mana, then play out Palinchron, untapping my lands, tap for 4 to bounce it back and.... realize I now only have the 7 mana needed to replay it, but not enough to net a profit to go infinite. I need another land, but now I've used High Tide. No matter, Pals back in my hand, safe, so I use Archeomancer to get back my High Tide and pass the turn. Next turn the Mogis guy gets finished off, leaving only 2 of us. I scry from Thassa and see a land. NOW I can win, I replay High Tide, cast Palinchron, gain a million mana, then I Rite of Replication, kicked, on Archeomancer, making 5 copies, returning High Tide, Merchant Scroll and a few other bounce spells to my hand. I cast Merchant Scroll, search my library for Blue Sun's Zenith and put it into my hand, then I cat it for 10000 on my opponent, making him draw his entire deck. He loses.
The truly ludicrous thing this deck wants to do now though, is add Enter the Infinite, Omniscience, and using Dream Halls as a shortcut to either, draw the entire deck, place Blue Suns back on top as the only card in my library from the Enter the Infinite, then do the infinite mana combo and play out Future Sight, allowing me to play the Blue Suns from the top of my library, where it will get returned to every time I cast it, meaning I can make every player draw their entire libraries and all of my opponents lose at the same time. I will not rest until I manage this feat.
