Hi all I'm refining my karlach haunted one deck and have a couple cards which I want to confirm the interaction. The cards are:

- Karlach fury of Avernus (kfa)

- Delina wild mage (dwa)

- Fire bending ascension (fba)

For the kfa and dwa interaction could I stack the dwa interaction first to make 1 or more copies of kfa which would then result in multiple combats or would I just make the token copies and only the original extra combat from kfa?

Fore the fba if I have the 4 counters can I copy the kfa extra combat trigger?

Thanks in advance will just help me decide what cards to get and what not!
