What should I do if I don't haven enough token cards for the amount of tokens I am summoning, what's acceptable as a replacement for those token cards? and should I sleeve my tokens a different color them my main deck?
You can use more less anything to represent tokens, as long as your playgroup is okay with it. I’ve seen players use everything from face-down unsleeved cards, to dice, to green and tan plastic army men to represent tokens before. If you use cards for tokens, sleeving them a different color from your deck seems like a good idea to me.
As far as tournaments and other sanctioned events go, you probably want to check the official rules for that event to make sure the way you’re representing tokens is okay. (Alas, I’m afraid rules for sanctioned events are not my forte.) When in doubt, asking the judge or TO of the event is always a good move.
