Sowing Thorns (Red)

When Sowing Thorns resolves, you will gain 1. Then it generates a Decompose effect that is an optional effect: you choose whether or not to banish 2 Earth cards and an action card from your graveyard when Sowing Thorns resolves. If you banish the three cards this way, you may search your deck for an Earth aura with cost less than the total you’ve gained this turn. You will reveal that card, then shuffle and put it on top.

If you choose to search your deck for a Earth aura card, you can fail to find an Earth aura card even if you still have one in your deck. Nothing is revealed nor put on top; however, you will still shuffle your deck afterwards.

To decompose, you need to banish 3 cards in total: two Earth cards, and one action card. The Earth cards may be action cards, and the action card may be an Earth card. Banishing an Earth action card will count towards either one of the two Earth cards being banished or the action card being banished, not both at the same time.

When resolving Sowing Thorns, there is no priority between any effects generated (e.g. gaining , banishing cards, searching, revealing, shuffling, putting on top).
