Bella, Atman Seeker

Whenever you cast a Saga, create two 1/1 green
and black owl tokens with flying. Then, you may
reveal cards from the top of your deck equal to
the amount of owl tokens you control. For each
swamp land exile it, gain 2 life, and deal 2
damage to each player. Then, put the rest on the
bottom of your library in any order.
{b}, {t}: For the rest of the turn, whenever
you tap a swamp for mana, add {w}{g}.
