Malicious Intent

The aura grants a repeatable evasion ability, but it routes that evasion through the enchanted creature's tap rather than its own combat. That distinction is the whole strategic shape: you are not making the enchanted creature unblockable, you are turning it into a tap-engine that clears a blocker off someone else, and the creature that taps to do so is sitting out the attack itself. The math rarely favors the aura player. Two-for-one card disadvantage is baked in (aura plus host both lost to a single removal spell), and the ability competes for the host's tap with attacking, blocking, and any other activated cost the creature already carries. What it does cleanly is enable a specific kind of alpha-strike: tap a creature you were not going to swing with anyway to peel back the one blocker holding off your real threat. That is a narrow window, and the design knows it; the effect is priced as a cheap, low-rarity combat enabler for a board-stall aggro deck rather than a serious removal substitute. Evasion-by-tapping has shown up in various shapes over the years, usually attached to a creature ability or a one-shot spell; stapling it to an aura was always the weakest delivery vehicle, because the aura asks you to commit two cards before the evasion does anything at all.
