mtg card font that player draws two additional cards. Font of Fertility (foil)

It just oozes value

Attacking an opponent with a 30/30 legendary creature possessing trample, double strike, and lifelink is not unusual in a Commander game with Dogmeat, Ever Loyal

However, there are caveats

Other options may not exactly combo with themselves, but the other combo pieces needed are so generic that it might as well be a 1-card combo

If you flip a second Illuna, you can add it to hand and then mutate it onto the first one for a double trigger (and no legend rule!) Its harder to see exactly what to do with Vadrok, Apex of Thunder , since one of the best spells in Jeskai to recast Deafening Clarion will also kill Vadrok unless you mutate it under something with better stats
