[semi-outdated]It's not a big deal. Back to the card. If you want to discuss any social faux pas, you can do that via PM's without airing your dirty laundry in public.[semi-outdated]
The ability costs just as much as Precog(upped), it is conditional (something has to have died) and doesn't allow you to see your opponents hand. Yes, it can be used every turn, but you are paying 3 or 4 for a creature with 3|3 as well.
If the ability cost was increased, maybe it could summon one of your creatures that died earlier in the game. Definitely cooler, but OP?
