I pulled the 6 star fire type and the 5 star dark type from the machine. Are they any good or should I trade for a monster. Ik that the yellow one when evolved can make a monster like verse unbindable which can be really helpful. Also the 6 star collab drop has 6 KILLERS! thats crazy for a farmable. ALSO are the two monster for the rainbow exchange worth it. I think im just going to trade for it. What r ur guys opinions?
