Bridled Bighorn

Most Mounts want a big rider to earn their saddle cost; this one manufactures its own. Each saddled attack spits out a 1/1 white Sheep, and a single Sheep is exactly half of saddle 2, so every combat rebuilds part of the tax that fuels the next one: the Mount funds the very activation that keeps it saddled. Vigilance is the hinge that makes that math practical within a single turn. Because the body attacks without tapping, it can still block on the crackback or, more relevantly, saddle another Mount during your post-combat main phase, since saddle is a sorcery-speed action you can only take on your own turn. The 3/4 frame does more work than the numbers suggest, since four toughness clears the reach of most early aggression, and survival is exactly what an incremental engine needs to reach its third and fourth attacks. What emerges is a go-wide engine wearing a midrange body: not a card that ends games on impact, but one that widens the board every combat step it lives through, converting white's long tradition of token generation into a saddle payoff rather than a standalone plan. Where most Mounts front-load their value in one big attacker, this one inverts the arithmetic, spending small bodies to make more small bodies until the saddle cost effectively pays for itself.
