- 9 September 2022You may tap any untapped nontoken artifact to activate Meria’s abilities, including artifact creatures that entered the battlefield this turn, even if they don’t have haste.
- 9 September 2022You must pay all costs and follow all timing restrictions for cards you play with Meria’s last ability. For example, you may only play a land card this way during a main phase of your own turn, and only if you haven’t yet played a land this turn.
