mtg final fantasy aerith Ultra Pro Playmat: VII return target creature card from your graveyard to your hand Aerith Gainsborough | Final Fantasy

So, if Summon: Fenrir enters with two lore counters on it, both its first and second chapter abilities will trigger, and you can put those abilities on the stack in either order

Valley Floodcaller is another very interesting card for decks including blue, even though it only allows you to break timing restrictions for noncreature spells

It can be a little unwieldy to use to maximum effect, but Kianne, Corrupted Memory lets you keep your mana open all the time

Once Sahagin has been blocked, casting a noncreature spell in order to cause Sahagin's ability to trigger won't cause Sahagin to become unblocked

Edit: In the meantime, Ravensburger added some more information and helpful videos to their own website

If there are any condition issues with the packaging, I will list them here
