"A technique pioneered by the legendary priest, Bon'Jovi, who kept his party members living by a prayer."
This card is based on the Priest ability from WoW of the same name, and the idea for hearthstone was to come up with a cheap spell like
Power Word: Shield
without the massive draw upside, but with a potential spreading upside if used on a turn where the player is attempting to make a lot of value trades. It can help your minions trade up and stay on the board.
Basically makes adjacent minions tar creepers
The effect spreads across minions as you kill them
can't be used proactively, which was the whole reason flametongue was busted, hence why i think this is balanced at 2 mana
This'd mostly be played in midrange, cos tar creepers don't mean anything for token/aggro decks, and control decks don't have minions in the early game.
But yeah, what do you all think?
The idea is that you get a random Shaman spell to your hand, that when you cast it... adds another random Shaman spell to your hand, that when you cast it... adds another random Shaman spell to your hand, and this effect repeats indefinitely for that one spell. The spell generated by Rehgar would also have a special effects layer over the card (like all of the "Shifter" cards), so you would know which card triggers this effect.
