icb- if its used on something with 0 atk, it would reduce it by 0, meaning the counter/timer would be 0, and not and any attack before going away, all it would do would be remove adrenaline should adrenaline be on a 0 atk creature for some reason.
like i said in the notes, i thought the cost was too high, was asking for feedback on cost, so thanks to those that offered up suggested numbers. ive had the idea for a few months now, but cost is a bit tricky. 2 and 3 respectively seems like it could be OK.
mahon- if you reverse time a dragon, for example, if they have sufficient quanta to play it again right away, all you really did was remove 10 quanta from them. however, if you slow/stop said dragon, you reduce its damage for a number of turns.
and yes, antimatter is clearly better, and that is fine. antimatter is better than most cards. if these cards were in the same element as antimatter, they would virtually useless by comparison. but theyre in
and its not a big deal.
