Reckless Velocitaur

Saddling and crewing are normally taxes: you tap creatures to activate a Mount or Vehicle, spending board presence to turn on a bigger threat. This Minotaur inverts the math by making the act of saddling or crewing pay you back. Do it during your main phase and whatever you activated gains +2/+0 and trample for the turn, so the setup cost that usually just enables an attack now also amplifies it. The main-phase clause is the real constraint: the bonus only lands when you saddle or crew before combat rather than reactively, which rewards committing to the attack early and forgoing the option to hold the crew action back as a surprise blocker-maker. Note that saddling and crewing tap this creature as part of the cost, so it fires the trigger once and then goes horizontal; getting a second bonus in the same turn means finding an untapper, not just having a second Mount lying around. As a body it is a plain 3/3, but it is built to be the crew member you want tapping down, converting the mounted-and-machined subtheme's inherent action economy into raw damage. The design answers a persistent problem with Mounts and Vehicles: the payoff for saddling often feels like a wash against the tempo you spend. Here the tempo spent is the payoff.
