Desert Wurms can't be blocked by creatures with flying. When Desert Wurms enters, create two 6/6 red Wurm creature tokens with “This creature can't be blocked by creatures with flying.” When Desert Wurms is put into a graveyard from anywhere, shuffle it into its owner's library.
Whenever you create one or more tokens, put a rift counter on Destabilizing the Rifts. As long as Destabilizing the Rifts has seven or more rift counters on it, creature tokens you control can't leave the battlefield.
{2}, {T}: Exile target creature. Return that card to the battlefield under its owner's control at the beginning of the next end step. Activate only as a sorcery.

Exile the top two cards of your library. Until your next end step, you may play those cards. Whenever you cast your third spell each turn, you may exile Devoted Artistry from your graveyard. If you do, you may cast a copy of it at the beginning of your next upkeep. (You still pay its costs.)
Target player discards two cards. Coalesce {8}{B}(You may cast this from your graveyard for {8}{B}. If you do, it enters as a Horror creature after it resolves. Exile it if it would leave the battlefield or not resolve.)
When Diao, Dragoon Captain enters, create three 1/1 red and white Warrior creature tokens. Whenever a creature you control attacks, invigorate 1. (Choose a creature with the least power among creatures you control and put a +1/+1 counter on it.)
Whenever a creature you control dies, put a loyalty counter on Dias, Freed from Belief. [0]: Create a 2/1 black Nightmare creature token with “This creature can't block.” [–X]: Destroy target creature or planeswalker unless an opponent pays twice X life.
When Diligent Fishermen enters, look at the top four cards of your library. You may reveal a creature card from among them and put it into your hand. Put the rest on the bottom of your library in any order.
Distorted (This creature can be blocked by tapped creatures but not untapped creatures.) Damage dealt to tapped creatures your team controls also causes you to gain that much life. Whenever a nontoken creature you own dies, create a token that's a copy of it.
