Sooooo you can infinite combo in Shaman now too
Cards Used:
2x fire plume harbinger
grumble
zola the gorgon
murmuring elemental
one or more elementals with a damaging battlecry (blazecaller is ideal)
Actual Requirements for OTK:
2 grumbles in hand
2 fire plume harbingers in hand
one of these 4 cards needs to have its mana reduced by 1
an elemental capable of dealing face damage
Setup:
play fire plume harbinger x2 , grumble, murmuring, zola on grumble (10 mana)
OTK: (assuming 1 fire plume harbinger has been reduced to 1 mana previously)
play 2x fire plume harbinger (grumbles cost 4) - 8 mana remaining
play a grumble - 4 mana remaining
play a fire plume harbinger - 3 mana remaining
play the other grumble - 0 mana remaining
from here you'll have a free harbinger, a grumble on board, a 1 mana grumble in hand and a 1 mana harbinger in hand and another elemental of indeterminate cost
you just keep playing the 0 mana harbinger followed by a 0 mana grumble until you reduce the cost of your damaging elemental to 1
then your cycle becomes:
0 mana harbinger > damaging elemental > 0 mana grumble
repeat until dead.
The issue is grumble's animation time and the number of cards that need to be played in order to make the lethal happen. Things can be sped up by using more than one damaging elemental in a cycle (kalimos animation and selection would also be slow)
- servant of kalimos can also be used to discover the second grumble
- having previously discounted damaging elementals helps speed up the combo
edit: 2nd murmuring can also be used to improve speed throughout the process, even dropping a full cost murmuring at the start of the combo is more than worthwhile
