Frustrating to play against if the loop is working, but often weak on killing power if it takes a lot of sacrificing to pay the upkeep.
I remember one game decades ago where I was slowly ground down by the tapping of a solitary Tim.
But yes it does kinda frustrate people. That's the downside of liking Magic because of it being fun to break as a system and not because you want to smash giant monsters into each other.
I don’t know what all was in it (I never played against it) but remember being regaled with tales of what happens when Opalescence and Humility come into play together as part of an effect that puts a bunch of permanents into play all with the same time stamp.
Aether Flash - Enchantment
Whenever a creature enters the battlefield, Aether Flash deals 2 damage to it.
Polyraptor - Creature - 5/5
Whenever Polyraptor is dealt damage, create a token that's a copy of Polyraptor.
Thanks for that memory.
King Arthur: What, behind the rabbit?
Tim: It is the rabbit!
King Arthur: You silly sod!
