Ah yes, my MtG peoples.
The funny thing is I used to run a Green-White-Blue Elf-Soldier Deck, abusing THE FUCK outta Tribalism (and Control) to basically overrun my opponent before they could do shit. Like on a good hand I could get something like 10 creatures out on Turn 4, and be able to keep them alive on my next turn's Attack Phase. I still have no idea how it worked so well together, but it did and I think a big part of that was that I didn't have a Key card, as I could easily power up any of my creatures to ridiculous levels...like turning a 1/1 into a 10/10 with trample, regen, first-strike, life generation, and flying (because fuck you, that's why). So I kinda connect with the MC on a personal level, Elves could get ridiculous, but they needed support before they really get going.
I'm actually looking through my old cards right now as I type this.
