Infinite hand size
Play peer into the abyss, then union of the third path, gain mega life, and then….. keep half your giant deck in your hand with no discard for any reason at all. Happened on ios, log files are a pain **********. I’d like to report that too..

There's lots of reasons someone can have an infinite hand size (i.e. not be forced to discard back down to 7 cards during their end step) — and lots of these are commonly played in decks with Peer of the Abyss. For example, Reliquary Tower (https://gatherer.wizards.com/pages/card/Details.aspx?multiverseid=519346)
