Teo, Spirited Glider

The looting trigger reads like a downside tucked into an upside, and the design makes that tension the whole engine. Any turn one or more of your fliers attack, you loot: draw, then discard. Ditch a land and you have smoothed your draw and nothing more; ditch a nonland and the card converts into a permanent +1/+1 counter on a creature of your choice. That single conditional turns a filtering effect into a build-around, because it rewards a deck stocked with expendable spells over one hoarding lands, and it asks you to sequence discards for value rather than convenience. The body is built for attrition rather than tempo: a 1/4 flier that can chip in for one every turn to satisfy its own trigger while the counters do the real accumulating. It is a fliers-matter payoff that does not demand a wide swarm, just a single evasive attacker to unlock the loot each turn, which makes it a quieter aggregator than the go-wide anthems that usually anchor this kind of tribal shell. The counter goes on any creature you control, not the attacker, so the growth can be pointed wherever it matters most: a mana dork you are turning into a threat, a blocker you want to survive combat, or the glider itself, which appreciates every point of toughness it can get given how little it hits for.
