Spycee because you won't win every fight he can be thrown away easily used similar to a dr card while being very scary if opponent hold stop bonus based strong ability cards or
Skeelz, not like his use limited to that,
Tula has many weakness and you don't need another fighter you already have 7, mixing in something else would be too costly for your support cards, in practice
Spycee was awesome often doing more than a dr card even could have for me.
Dahlia vs
Selma much debated topic but it is pretty simple as pirahna you can't sit on your puny dmg you want to win rounds you can't even use dr, 8 vs 7 power is already a big one mostly translates to +1pill to win,
Selma is not bad but i would only use her if i need the first rounds for other cards, courage, poison etc..
