Shadowverse

The Roach 2.0 is an incredibly overpowered, monstrous creature that can obliterate you as early as round six. You'll never be safe from it, even at full health. It strikes fear into the hearts of everyone in unlimited mode and even in rotation.
And Elana... Well... She counters it.

Actually, not exactly, but it's problematic for the Roach to eat through a thick ward, especially if there are other units around and it can't push them away with Mischief.
