I've been posting a lot in this thread, but: Reverse Time is similar in strength, effect, and versatility to Silence.
Reverse Time:
*denies opponent a draw for 1 turn
*can be used to help prevent deckout
*denies all drawing when chained (assuming no counter)
*removes creature buffs and forces opponent to repay the cost of the creature
*can be chained indefinitely by using Eternity
*works well with Nightmare
Silence:
*prevents opponent from playing cards for 1 turn
*can be used to prevent Miracle, Fractal, etc.
*prevents opponent from playing anything when chained (assuming no counter)
*works well with Nightmare
Since Silence costs 3
/ 2
, we should either buff it or nerf Reverse Time.
