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
The original list I netdecked from Autumn Burchett had four copies each of Cache Grab and Say Its Name, but after bricking completely a couple times, I made the switch to Moment of Truth and Impulse
We just have to be careful not to deck ourselves with Chasm Skulker
Other removal spells are made unreliable by their dependence on specific gamestates
In addition, everything that can be is done in WUBRG order
