Wonder, meanwhile, will give all those Illusions some much-needed evasion, and Murmuring Mystic can reinforce the Illusion army with extra creatures
And in Expanded in particular this is very easy to pull off with a card, Hypno-Toxic Laser (PLS 123/135), which poisons your opponent's Pokemon and puts them to sleep on the flip
Offering card draw, removal, and a somewhat expensive, win condition, Vraska, Betrayals Sting does it all
In addition to that Atem's deck would of course be including some cards that would keep his opponent at bay till he gathered his monsters to summon the gods and so cards that trigger destruction like Yomi Ship would come in handy in that situation
Instead, I want to fill my deck with as much incidental interaction as I can, and thats pretty easy with the likes of Aether Meltdown, Deadlock Trap, and Confiscation Coup
