These are unique cards to championship decks that Wizards used to sell, which are explicitly not legal in a tournament setting
Wound Reflection, Warlock Class, Bloodletter of Aclazotz, and anything worded like this doubles your damage, which is sometimes enough to one-shot players with commanders like Heartless Hidetsugu or Alpharael, Stonechosen
Flying seems particularly useful here, so if you opt to go this route, I may consider going up to 4 Wing Splicer
I dont think its quite at its best here because theres a lot of potential in its secondary ability of cheating out a large creature or two, yet theres nothing worth cheating out in this deck
I am just curious is it 50% Thick and 50% thin, is it 60/40 one way or the other etc
Of course, they do it FOR SCIENCE
