Spearpoint Oread

The trick that makes this common more than a filler beater is that its keyword and its stat boost are one and the same package. Cast it as a 2/2 first striker and you have a body that trades up in combat; pay to bestow it and it folds into your board as an Aura, handing another attacker +2/+2 and first strike while staying a creature-in-waiting if the host dies. First strike on an enchanted creature is what turns a static buff into a one-sided damage exchange, since the bestowed creature now hits before anything its size can answer back. That stacking is the payoff. On a host that already strikes first the redundancy is wasted, but on a vanilla 3/3 it converts a fair fight into a clean kill. The six mana to attach is the tax you accept for two-for-one insurance: when removal answers your beater, you get a creature back instead of a dead Aura. It is workmanlike rather than marquee, the kind of design bestow needed at common to make the mechanic legible: cheap creature now, combat-warping aura later, never a total blowout when the opponent holds an answer.
