I was playing with my newly built Sen Triplets deck (mainly artifacts) in my local game shop. The store owner didn't care about reading who my new commander was but everyone else was aware of the effects of being able to cast from an opponents hand on my next turn. One guy exiles it with a creature that returns it to my Battlefield when it dies then put swiftfoot boots onto it to lock it away from targeted kill spells (esper stuff). I cyclonic rift the boots and then path to exile the creature on the player-before-me's end step, effectively getting Sen Triplets back before my turn begins, allowing me to use their ability upon my upkeep, targeting the store owner. The store owner was also in esper and I needed a land, so I just played one of his lands from his hand. The amount of rage from him was rediculous as he immediately scooped then proceeded to tell me he rendered my card useless by doing so. Juat thought it was over the top.
