First-pick, first-pack, I would speculate on Mickey Mouse Detective and then prioritize six-drops and seven-drops even more highly, but later in the draft it would depend on the cards I have picked thus far
A pile of combos happens in those Jan Jansen decks with cards like Liquimetal Coating to turn it into an artifact and then begin ripping with a Goblin Bombardment in play
For example, if youre using Kiora, Sovereign of the Deep or Kenessos, Priest of Thassa you should probably be using Pearl Lake Ancient
While Kari Zev wasnt an incredible card in terms of power level, it put in solid work here and there, and when it did people saw, and loved, Ragavan
It deals only 2 damage to Ageless Guardian
Thats insane value, and even if you lose your 4-powered creature, you get to put a +1/+1 counter on a 3/3 and start the process over again
