Nokstella, City Eternal

This land enters tapped.

All basic lands lose all abilities and become Wastes with "{t}: Add one mana of any colour. Whenever you cast a spell using coloured mana produced this way, it gains Suspend 1. (If it already has Suspend, do not add another time counter.)"

{1}{u}{u}{t}: Copy target instant or sorcery you control, then exile that spell with three time counters on it. It gains suspend.
