Blind-Spot Giant

A 4/3 for three mana is a genuinely aggressive rate in red, and that rate is exactly the bait: the body can neither attack nor block without a second Giant on your side of the board. Alone, it is a 4/3 frozen out of combat by its own static restriction until the tribe shows up. That conditional does the same structural work a heavier mana cost otherwise would; the design pays for an above-curve stat line not with extra mana but with a deckbuilding tax, refusing to slot into a generic red beatdown shell. You either commit to a critical mass of Giants or you leave it home. As a tribal payoff it inverts the usual lord arrangement: instead of buffing the team, it requires the team to already exist before it earns its place in combat. The friction is binary rather than scaling, which makes it a clean threshold test of whether a Giant build has reached playable concentration. There is no partial credit, no incremental upside for half-committing. Build the deck it wants and you get a hard-hitting three-drop; build anything else and you get a Giant-shaped statue.
