Lurking Crocodile

Two conditional mechanics stacked onto one body, and they pull in opposite tempo directions. Bloodthirst rewards you for having already connected: cast it on a turn where an opponent has taken damage and it enters as a 3/3, which means it wants to follow your aggression rather than start it. Islandwalk asks for an entirely different matchup, doing nothing against four-fifths of the color pie and converting into a guaranteed hit only when the defending player is on blue. The ceiling depends on two unrelated conditions aligning: an opponent already bloodied this turn, and an opponent on Islands. When both land, a hard-to-block 3/3 for three mana is a respectable clock. When neither does, you have a French-vanilla 2/2 carrying two keywords that both happen to be doing nothing. That conditionality is the heart of bloodthirst as a mechanic: a kicker-like bonus paid for with sequencing rather than extra mana, the counter banked at resolution and locked in regardless of what the board does afterward. Islandwalk belongs to an older species of color-hate rider, the kind that quietly turns a green beater into a weapon aimed at one opponent and inert against every other. Neither half taxes the deck around it; both lean entirely on the board cooperating, and they rarely cooperate at the same time.
