­Challenge # 083

So instead of dying during the combat damage step, it dies as soon as SBEs are checked during your second main phase. I don't see the point. Also, why keyword a drawback? It just draws attention to how this is worse than a vanilla 5/3.

"~ must attack if possible. When ~ attacks, it gains indestructible until end of turn." seems to be what we're going for here. Though I find it kind of funny, nesting a keyword in a keyword.

Eh, it's not a keyword people would be fond of; but I can see it. I read it more as "I enter combat, and white can't stop me; I will deal my damage; and then I die."

It's odd that it's only a very few effects it bypasses though - you can still Lightning Bolt this before combat starts.

It is kind of funny. In theory, you don't know whether the creature will attack or not before you lightning bolt... but... oh yeah... I guess he will.

"As long as this creature is attacking, prevent all combat damage to it" actually does makes sense on a berserker. You can kill it, just not wound it in battle. That by itself would be a good mechanic IMO.
