Warden of the Inner Sky

Every activation asks you to tap three permanents (creatures or artifacts) that would otherwise be attacking or blocking, so growing this thing is never free: it is a tempo decision, each crank spending the resource combat wants. The sorcery-speed clause closes the loophole that would break it, since you cannot tap the team down defensively and still swell the body on the crackback. What you build toward is a two-stage payoff. The +1/+1 counters stack smoothly (1/2, then 2/3, then 3/4), so no early activation is wasted on the stats, but the evasion package stays gated: only at three counters does the creature gain flying and vigilance at once. That threshold is the whole arc. It begins as a scrying wall that grows while it waits, then crosses into an attacker that no longer risks itself to swing, since vigilance feeds its own untapped state back into the fuel pool it demands. The Scry 1 riding on each activation keeps a slow build from stalling: even while you are only inching toward the flying threshold, you are filtering draws, so a clogged board still does work. The ask is a wide, patient board willing to spare three permanents a turn and let the counters accrue, a heavier commitment than a one-drop usually earns, which is why the reward is front-loaded with scry the entire way up.
