The effect is worth it at the beginning of most games
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
It also tends to function a little differently depending on what colours you are using
Hitmonlee holds a niche as one of the few Fighting-type holos from the early expansions, and Haunter benefits from being part of the beloved Gastly evolution line
Goldvein also has Vigilance, Trample, and Haste, making it a scary card to see played, especially when the X cost is so easily raised by the Commander
