4 mana 8 damage of rush seems decent, or kill a 4 health minion, summon a 4/2 is just kinda okay goodish.
Still, quite a possible 8/4 of rush stats for 4 mana. maybe?
I’d say in this case you may as well call it 8/2 in stats, the health of the first doesn’t matter if you only get the second 4/2 if the first dies this turn after all.
it feels like death rattle, but it’s control card, perhaps good in big dh
i doubt this will see play until the next rotation.
for control purposes the 3/3 deathrattle into two 1/1 taunts most of the time is just better to stall while offering 1 more token.
only exception would be if boards with multiple 5/6 health creatures would become commonplace.
Flanking strike but better; i think this will be an auto include in most DH decks, expecially big demon
that warrior mumy with rush and reborn was a 3/2 then 3/1 and i believe its was 4 mana it saw a bunch of play. this is a much better version really
