I have an unevolved (0/1) Cloudfin Raptor on the field and i play a Bond Beelte. Can i put the counter from the beetle on itself and still evolve the raptor?
No. The creature must have greater power or toughness the moment it enters the battlefield. Bond Beetle enters without the counter as a 0/1, then its ability triggers. It gets the counter only when this ability resolves; at this point is too late for any Evolve ability to trigger.
