The 20/20/20 Rule First, let's talk about the 20/20/20 rule

Eumidian Wastewaker Whenever Eumidian Wastewaker attacks, it makes both you and your opponent discard or sacrifice, often turning extra lands into card draw

Oviya offers some solid upgrades to Elvish Piper, adding Trample to Creatures attacking your opponents, and potentially adding +1/+1 counters to Artifact Creatures (or Vehicles) you sneak in

Note, however, that youll get only 2 Rare cards at most (with 1 or 2 Rares per pack), along with 3-5 Uncommon cards, 8-9 Common cards and 1 Land

Jinx and Kangaskhan are secondary attackers here who can benefit you situationally, but the real star of the show is Mewtwo and its Psydrive attack
