Play Taigam, Master Opportunist
Play Xho Cai, Flickering Talon (commander)
Use any "blink effect" - in my case, both ephemerate as well as Xho Cai's ability produced the following bug:
Any creature I would exile, that should be immediately returned to the BF, is exiled with 4 time counters on it instead - even though they weren't exiled by Taigam, but other effects.. Extremely annoying and detrimental to a deck that works off of this commander's effect!
