Goblin War Paint

Two mana for +2/+2 and haste reads like a worse Rancor until you weigh what each half of the rate is actually buying. The +2/+2 is fine; the haste is the part that justifies the card, because it turns a freshly cast creature into an attacker the same turn and lets an aggressive deck convert a stalled hand into immediate pressure. The cost of that speed is the cost every Aura pays: two-for-one risk. Spend the card to enchant a creature, and a single removal spell answers both, which is why this kind of effect never quite competes with the equipment that does similar work without the downside. The lineage runs straight back to the cheap, all-upside power-and-toughness Auras of the earliest sets, the ones that gave a beater a swing in stats and asked nothing in return except that you not get blown out. Haste is the wrinkle that distinguishes this one: it is a tempo enabler dressed as a pump spell, built for a deck that wants to deploy a threat and attack with it before the opponent can untap. Outside that narrow tempo mission, the math rarely favors committing a second card to a body that was already on the board.
