Deep-Cavern Bat itself isn't OP. Unfortunately, the meta in Standard atm just has way too many cheap & ubiquitous hand-hate cards.

Aside from Leyline of Ressonance (which most definitely should be banned) giving the possibility of turn 2 wins, I haven't seen any arguments for any single-card outright bans in Standard hold water upon closer scrutiny.

I'm keeping my eye on Leyline of the Guildpact for a possible ban. I think there are possibilities with Dragons there which would make an entire class of very, very unfun decks to play against/with.

I do think the current meta in Standard is, however, so broken I've stopped playing it remotely seriously. It's not fun to play in an environment with:

- So much cheap/ubiquitous hand-hate

- So many cross-color abilities that smear the color archetypes into an ugly Impressionistic melange

- So many blind (hidden) zero-skill two-card combos (akin to a weaker Splinter Twin) that you can't see coming and are near instant wins or, at the very least, a win in one. Two examples are all the sneaks for Valgavoth, Terror Eater or Manifesting + Splash Portal.

- Way too much aggro such that too many games have trivial board states and are decided by a series of route memory plays and responses in, at most, 3 turns. Given that there are so many aggro cards and they are so cheap (usually 1R), it's going to be difficult, if not impossible to address this. Atm, I think the only "solution" will be to wait for two rotations. This area, particularly, is where WotC used really poor judgment.

This meta is not what I consider "good Magic". I think history will judge the Duskmourn meta as one of the worst in the modern era.

Seriously? THAT is the card you think is breaking the format right now?
