I have been summoned.
There are 2 debates:
Is this an other or a Death card?
What is a balanced cost?
Is this an other or a Death card?If a card is cast using a lot of non
then its Cost is thematically non Death.
If a card is powered using decay or something that is decaying then it's thematically Death. (uh oh)
If a card is added to a series it should maintain the symmetry of the series. (More support for Other)
If a card is designed with the purpose to create Death Triggers then that aspect is thematically Death. (2v2?)
Verdict: It is conflicted. This is a problem and it is the reason both sides are sure they are right on this issue. I ordered these reasons from most to least important in my opinion. The result is that while conflicted to a fault, it fits best as an other card.
What is a balanced cost?Nova + Decaying Dragon | Dragonic Horror = 27|40 damage
Cost for OTK: 3 Novas, 4 Decaying Dragons | 3 Dragonic Horrors = 7|6 cards for a 3|4 turn win. (Wow expensive but very powerful)
What can Immolation do with 7 cards?
2x Immolation, 2x Sacrifice, 1 Crimson Dragon, 1 Grabiod [Earth Mark], 1 Lycanthrope = 12+1/12+2+6/12+8+6 = 13+20+26 = 59 damage in 3 turns
(Results in a turn 5 overkill win but is more likely to occur)
By theory:
See ZBlader's post about my theory. I would have assign the ability a +0 not a -2 since the game is over so fast. This results in final costs of 13
|13
which would reduce the god hand (unlikely to occur best hand) to a turn 4 victory and increase a similar cost Immolation hand to a similar victory.
Final Conclusions: Changing it to Other due to high (6+) non
investment and perhaps increasing the cost to 13
|13
