Dragon Tyrant

Ten mana for a 6/6 that demands four red every upkeep just to stay on the table: this is the dragon built as a reward for reaching the top of the curve and then proving you can keep the gas flowing. The upkeep tax is the central tension. A double-striking flyer with trample is, in raw combat math, a game-ender, but the card refuses to be a haymaker you cast and forget. It asks for a continuous stream of red mana, both to survive each turn and to grow itself, so every point past the base 6/6 is bought live during your attack step. Double strike is what makes the firebreathing terrifying: each adds one to the power, and because both the first-strike and regular damage steps see that bonus, every activation lands as two extra points instead of one. In an era obsessed with raw card velocity, this was the finisher for a deck that simply wanted the largest possible threat and had the mana to feed it. The sacrifice clause holds the rate accountable: untap with too little red and the tyrant devours itself, so it is only ever as strong as the red engine standing behind it. The firebreathing and the survival cost draw from the same pool, which means each attack is a live negotiation over how much you can pour into the air without starving the next upkeep.
