Thassa, God of the Sea {2}{U}

Notes and Rules Information for Thassa, God of the Sea:

• Activating Thassa's last ability after the target creature has been blocked won't change or undo the block. (2013-09-15)
• Numeric mana symbols ({0}, {1}, and so on) in mana costs of permanents you control don't count toward your devotion to any color. (2013-09-15)
• Mana symbols in the text boxes of permanents you control don't count toward your devotion to any color. (2013-09-15)
• Hybrid mana symbols, monocolored hybrid mana symbols, and Phyrexian mana symbols do count toward your devotion to their color(s). (2013-09-15)
• If an activated ability or triggered ability has an effect that depends on your devotion to a color, you count the number of mana symbols of that color among the mana costs of permanents you control as the ability resolves. The permanent with that ability will be counted if it's still on the battlefield at that time. (2013-09-15)
• When you scry, you may put all the cards you look at back on top of your library, you may put all of those cards on the bottom of your library, or you may put some of those cards on top and the rest of them on the bottom. (2013-09-15)
• You choose how to order cards returned to your library after scrying no matter where you put them. (2013-09-15)
• You perform the actions stated on a card in sequence. For some spells and abilities, that means you'll scry last. For others, that means you'll scry and then perform other actions. (2013-09-15)
• Scry appears on some spells and abilities with one or more targets. If all of the spell or ability's targets are illegal when it tries to resolve, it won't resolve and none of its effects will happen. You won't scry. (2013-09-15)

• The type-changing ability that can make a God not be a creature functions only on the battlefield. It's always a creature card in other zones, regardless of your devotion to its color. It's always a creature spell while it's on the stack. (2020-01-24)
• As a God enters the battlefield, your devotion to its color will determine whether any replacement effects that affect creatures entering the battlefield apply to that God. Because replacement effects are considered before the God is on the battlefield, the mana symbols in its mana cost won't be counted when determining this. (2020-01-24)
• When a God enters the battlefield, your devotion to its color (including the mana symbols in the mana cost of the God itself) will determine if a creature entered the battlefield or not for abilities that trigger whenever a creature enters the battlefield. (2020-01-24)
• If a God stops being a creature, it loses the type creature and the creature type God. It continues to be a legendary enchantment. (2020-01-24)
• The abilities of Gods function as long as they're on the battlefield, regardless of whether they're creatures. (2020-01-24)
• If a God is attacking or blocking and it stops being a creature, it will be removed from combat. It won't rejoin combat if it resumes being a creature later during that combat. (2020-01-24)
• Counters put on a God remain on it while it's not a creature, even if they have no effect. (2020-01-24)
• If an effect causes a God to lose all abilities, its ability that causes it to stop being a creature still applies if appropriate. (2020-01-24)
