Riquezas explosivas

Explosion of Riches goes on the stack without a target. While the spell is resolving, you draw a card, then each other player in turn order chooses whether to draw a card. After that, each other player who chose to draw a card does so. Finally, Explosion of Riches's reflexive triggered ability triggers for each card drawn while it was resolving, and those abilities are put on the stack with random targets chosen.
