@CA with those 3 enchantments on the field, you can do several things
First one:
1) Exile a creature with Parallax Wave
2) Exile Parallax wave with itself
3) Let the self-target resolve. LTB effect occurs, it comes back with 5 counters, due to own trigger.
4) Original return trigger occurs, but the original wave is gone, so it's countered. The creature is exiled permanently.
Second
1) Same first step
2) let the removal trigger resolve, now have the wave exile itself, LTB trigger occurs. It comes back with 5 fresh counters, along with the creature(s). Abuse with ETB effects.
Third
1) Exile 5 lands with Parallax Tide
2) In response to exiling those lands, exile Parallax Tide.
3) The lands are gone as a new Parallax Tide comes in.
Fourth
1) Exile 5 of your lands with PT
2) Let triggers resolve
3) Exile Parallax Tide with Parallax Wave. Enjoy 5 untapped lands and infinite mana to fuel yourself.
Also, if you want to test your deck, I recommend Cockatrice- it allows you to test out your deck online, without spending any extra money.
