One of my favorite combos:
4 charmanders, 2 charmelians, 1 charizard
4 growlithes, 2 arcanines
lots of fire energy, a couple double colorless, and a couple fighting energy (around 20 energies altogether)
4 professor oaks
4 energy removals
as many super energy removals as is legal (still 4, or is there a limit?)
Maybe some potions or computer searches
Haven't played this since the first set.
Brings back memories.
