Once a Companion enters the game, they stay in it and wont return to the zone where they originated from
The best ones to do that are artifacts, so any drafter can use them, but some colored ones look interesting as well: And to help with critical mass, there are some Changelings and clones that are commonly used anyway: Ideally, the effect I want to achieve is: - 1-2 decks per pod have minor tribal themes (say, RG Beatdown with Krenko, Mob Boss, Siege-Gang Commander and Goblin Warchief doing cute things) - In about 50% of the drafts, a dedicated tribal deck is drafted, running the generic tribe enablers (White weenie running mostly Soldiers with Adaptive Automaton, Harsh Mercy, Mutavaultand Obelisk of Urd) - Once in a blue moon, someone puts together Shriekmaw, Mulldrifter, Flickerwisp, some clones, changelings and the tribal cards and makes a crazy 4-color Elementals blink deck that's bad but loads of fun
How would you build it differently
Personally, I think the best bet would be if we see these show up either in promo packs or if they are able to be pulled in the Reverse Holo slot like Shinies or Amazing Rares
Lets say you want to ensure dealing damage to each player every turn
