Flying with wings requires active concentration so floating around is out of question. You split up, fly up for a moment and descend back down after looking around. There's a hill in north of you and shortly after that the forest ends and a swamp begins.
Now finding mind of your opponent proves challenging because there's quite many minds around. Bear, elks, frogs, birds... But ultimately you find one intelligent mind and enter into it.
Arthur finds himself on world that is a sky. Out there is a human flying around, having appearance similar of Generally me as you saw him in the tournament hall.
Bert enters into dark world filled with hurricanes and rain.
The world Carl enters in is the tournament hall where your opponent is looking over his cards. There's certain sense of regret.
Dylan... Well, it is a mismatched collection of various worlds. Both primitive and modern.
Ernie fails to enter into his mind. Because the "heart beating division" is involuntary activity that mind barely has any control over.
Fred enters into world of joy of flight, shadowed by hint of regret.
Now burning those worlds created by mind of your opponent is a bit problematic. Firstly your appearance in these worlds is same as your self image, which is that of human and humans don't really burn anything. And burning mind is different power altogether.
Since Ernie failed to enter into Generally me's mind, the plan to summon automaton fails as well.
Sky screams and meteors begin falling. Luckily all three fell on north west away from you.
