Confine the Fiends

Seal up to two target creatures you don't control
with mana value X or less. (Exile those cards with
a seal counter on them. For as long as those cards
have a seal counter on, they have ''Exile a card from
your hand, Remove a seal counter from this card: Put
this card into your hand. Activate as a sorcery.'')
If you control exactly one creature, remove all
seal counters from sealed cards players own in
exile. Then, draw that many cards.
