you are basically killing the creature and making the next card in your opponents deck a "new" copy of that creature
all quanta investments, buffs etc are gone and on top of that you have to pay the quanta cost to field the creature again
i dont know for 2 quanta being able to do that seems like its a bit cheap no?
I have to agree that it is a bit cheap. RT is probably mostly responsible for making buff-based strategies unviable. However, RT is also pretty useless against a lot of mono rush decks (aether of course, but also fire, air, and darkness).
It's not useless at all against a rush. You delay your opponents creatures a lot and it is sometimes all the advantage you need to beat your opponent. Not to mention you prevent your opponent's draw which is vital in rushes.
Yes, not entirely useless, but:
1. You do not delay your opponent's creatures as long as they have the quanta. Mono decks commonly have extra quanta, particularly in the mid-to-late game. An exception is cremation-based decks, which RT is effective against.
2. The opening hand is more vital than draw in rushes. Conversely, draw is more vital than opening hand in control. Control decks are the ones that need the draws so that they can set up a way to maintain card advantage before they die from the rush's opening hand. RT is better in rushes than in control decks for this reason.
