This week, were going to be focusing on the mechanic from the Dimir guild: surveil
For example, cards like Angel of Jubilation and Yasharn, Implacable Earth can be used to prevent an opponent Sacrificing their own creatures, and Tarjuru Preserver or Sigarda, Host of Herons stops foes from forcing you to Sacrifice creatures
It exiles cards for each opponent when it enters, and its coven ability word lets you recover them if you control creatures with different powers
1 Ionize
Again, four more land re-prints
(The Discard Pile is where knocked-out Pokemon, any Energy that was attached to them when they were knocked out, and all used Trainer/Supporter cards are piled up.)
