Torens, Fist of the Angels
Two mechanics point the same way here, and the loop between them is the entire design. Every creature you cast spawns a 1/1 that also has training, so the board doesn't merely widen: it develops a hierarchy where each small body is a candidate to grow behind a larger attacker. Cast a beater and the tokens it made can climb on the next swing; cast a run of cheap creatures and the count itself becomes the threat. This sits in a green-white lineage that has long tried to marry go-wide token production with a payoff that scales, and the elegance is that the payoff and the go-wide engine ride the same 2/2. A deliberate friction is built in: training only fires when a creature attacks alongside something with greater power, so a board of nothing but 1/1 tokens grows no one until you commit a real attacker to lead. That demands a curve mixing cheap fodder with a few larger bodies to pull counters through, rather than a pile of same-sized tokens spinning in place. The cleverness is that casting creatures does double duty: it advances the aggression and it feeds the training triggers on everything already deployed, so a single spell can both add a body and level up the board behind it.
