Caenum, Wild Magic Prodigy

Whenever you cast a spell each turn with cmc {4}
or greater, roll on the surge table for each spell cast before it.
Apply each surge effect to a permanent you control, you may not pick the same target twice in a row.
If a surge effect is applied to a permanent affected by
2 or more surge effects, you may pick a permanent
on your opponent's field.
When Caenum is dealt damage, transform Caenum.
