Ursten, Adventurer Mystic

Whenever a card causes you to search your deck
for one or more lands, create a token that's a
copy of target permanent except its a 1/1 blue illusion creature in addition to its other types and colors and it has 'when this permanent becomes
the target of a spell or ability, sacrifice it'
{1}{u}{u}: Target illusion you control gains flying
until end of turn.
