A two-mana cantrip that only taps one creature is far behind Modern's efficient interaction; it may receive brief spell-density testing in Izzet shells.

Could be wrong if A new spell-payoff or creature-tapping synergy could make its low-impact effect worth a slot.

Legacy's one-mana selection and interaction make this markedly less efficient than Consider-level utility, while a temporary tap rarely swings games.

Could be wrong if An unexplored blue tempo shell could value an extra instant cantrip that also breaks a combat step.

Drawing a card keeps the cost low, and tapping a blocker can create a combat window, but it is much narrower than Pauper's premier cheap spells.

Could be wrong if Tempo decks may find the combat swing and spell count more valuable than its modest rate suggests.

One temporary tap effect has little multiplayer impact, and scry 1 plus a card is too small for a two-mana singleton slot.

Could be wrong if A commander specifically rewarding cheap instant cantrips or tapping creatures could create a niche.

Instant-speed tap plus a replacement card can force attacks, blunt an attacker, or buy a crucial turn; it is solid tempo glue, not a bomb.

Could be wrong if Unknown set speed, creature sizing, and tap/untap synergies could move this substantially in either direction.
