It is infinite creatures, however it is only infinite in potential only 1-2 are on the field per death (unupped) although they will continue to spawn themselves.
Unupped
each death results in 3 damage per turn and Absorb
(only 1 damage the first turn and no absorb)
This is easily able to be balanced. (In fact I think a casting cost of 5
is sufficient provided Fire is the best element for these Zombies. I obviously disagree.)
Upped
Turn | Number of Flames | Total Cost | Total Damage |
1 | 2 | 0 | 4 |
2 | 4 | 2 | 16 |
3 | 8 | 6 | 40 |
4 | 16 | 14 | 88 |
5 | 23 | 30 | 166 |
6 | 23 | 53 | 254 |
The exponential growth of the upgraded is harder to balance and requires a much higher cost.
I agree with the previous suggestion to make the upgrade a simple 1-2 cost reduction.
Nvm author did not intend loop.
It looks good as a simple Fire version of Graveyard.
