I'd love to have been a fly on the wall during the design process for this deck, as it must have been quite the challenge to fulfill this brief and create a functional (if meme-y) deck that players are going to want to use
You can make a "Counter-Squirrel" aggro-control deck, a tempo-based deck with cards like Aether Burst and Temporal Spring, or a threshold deck with cards like Merfolk Looter, Mental Note, and Careful Study
Just Here For A Good Time Of course, Deadpool, Trading Card will find plenty of use at more casual MTG tables too
While the more expensive variants come with extra goodies, such as Brokers Confluence , which can counter the madness trigger, and either proliferate or phase creatures out
The Mycosynth Gardens Whatever you want A good land is always a worthwhile thing to have in MTG
Then looking at Inalla, Archmage Ritualist and imagining how in the endgame, I would cast Rite of Replication on a wizard in play and drain a player out from 14 or more life unexpectedly
