Obstinate Familiar
Drawing cards is the most fundamental resource engine in the game, and this small Lizard exists to put a switch on it. The optional-skip clause is the whole hook: it answers a narrow class of effects that turn drawing into a liability, the forced-draw and symmetric card-flow engines that were thick on the ground in this era's design. Howling Mine, the various group-draw pieces, the wheel effects that refill both players: against any of them, this body lets you opt out of the draws that would deck you or accelerate a loss while your opponent keeps absorbing theirs. The "may" preserves your normal draw step whenever the card is something you actually want, so the ability never turns into a liability of its own. What it can't do is act on its own initiative; it does not tax the opponent or stall their engine, since they still draw exactly what their cards give them. All it does is sever the symmetry, letting one player keep the upside of a forced-draw effect while the other simply walks away from the downside. That is the entire mechanical role a one-toughness creature for a single mana fills, and it fills it cleanly. The body is too small to matter in combat and the ability too specific to matter without a forced-draw effect across the table, but when that effect is present, it quietly converts a clock that ticks for both sides into one that only counts down for one of them.
