By adjacent, I mean any cards that are in contact at any pane. So, ups and downs also count. With the way the cards are outlined in Elements, a card could actually gain from 6 cards (if I'm not mistaken).
Krathos,
I actually wanted to use Fusion in place of Perfusion, but it would require "selecting two targets," which does not exist in the game interface as I hear, so I had to come up with something else.
I can see that this skill does not sound very fancy, but in reality, I think it can be pretty powerful. If you had Pharao and used this skill on a Scarab, you instantly get a very strong Scarab. You can use it with Oty too. Place Oty next to Armagio, and what do you get? Oty that can devour pretty much any creatures!
Moreover, if you have 2 of this Avatar and used each skill in one turn.... You can do the math on how quickly you can make powerful monsters.
