Fires of Yavimaya

Granting haste to a whole board is something red and green keep returning to, but this packaged it cheaply and gave it a back end most haste enablers lack. The first ability does the obvious aggressive work: every fattie you drop attacks the turn it lands, every topdecked threat is live immediately, and the deck stops caring about the summoning-sickness tax that usually punishes ramp strategies for cheating big creatures out early. The sacrifice clause is where it earns the slot twice. It is not a dead enchantment once the board has stabilized or once the haste no longer matters; it converts itself into a +2/+2 pump at instant speed, doubling as a surprise blowout in combat or the last two points needed to push a swing through. That gives the card a clean arc: it accelerates the early game, then cashes itself in for a late-game trick when its passive utility has dried up. The dual nature is the design point, an enchantment that both enables a tempo plan and provides its own exit value, so it never quite becomes a wasted slot. Gruul midrange and ramp shells built around oversized threats are exactly where that combination of always-on aggression and a built-in finisher earns its keep.
