Replace for draw, like Blaze hound and (always hold onto) Tectonic Spikes.  After you find draw, unload your hand with buff minions or hatch a ripper and buff.

Flash Reincarnation into Elucidator buffed with Amplification to face deals 7 and cost 3 and you still have a 7/4 on the board.

Flash Reincarnation into Makantor buffed with Amplification hits with frezy, deals 6 to all enemies around, cost 5 and you probably have at 6/4 on the board(depending what you swing into, hit the general or minion with the least attack).

If you are holding Tectonic Spikes, no be afraid to buff minions.
