Since yesterday, we've known that Thassa, the blue-aligned sea goddess of Theros, wields a two-pronged spear, a bident named Dekella. According to the backstory, her mastery over the tides is contained within this magical item, and she guards it jealously. The revelation of the gods' weapons prompted, of course, a flurry of speculation, and now it seems Dekella has been revealed on the September Friday Night Magic promo poster, giving us insight into what the rest of the cycle will be like - and it's nothing like we thought.
Here's the card text:
Bident of Thassa 2UU
Legendary Enchantment Artifact (Rare)
Whenever a creature you control deals combat damage to a player, you may draw a card.
2U, Tap: Creatures your opponents control attack this turn if able.
The wills of mortals shift as the tide ebbs and flows.
Okay, get your snickering about the similarity of the name to "Bidet of Thassa" out of the way now. First issue first - it's a little strange that the full name isn't "Dekella, Bident of Thassa," as if Creative didn't get a chance to put the weapons' names on their card versions. The second glaring thing is the type line - "Legendary Enchantment Artifact," which is a combination of types that most thought R&D would never do. What's the point, they said, since enchantments and artifacts are almost identical in gameplay terms, save for aesthetics? This is, technically speaking, an enchantment that taps, which breaks some supposedly fundamental design rules (simply because it seems wrong somehow) and that seemed to be one of the never-agains that cropped up in the Future Sight futureshifted cards. Then again, it's also an artifact (even if it's a blue one, hello Esper!) so tapping is probably allowed.
As far as the card goes, it's a better Coastal Piracy (how's that for a card we haven't seen in a while) that also has some Siren flavor in the forced-attack stuff. Blue gets this from time to time nowadays, even if it's not a regular thing; forcing attacks is almost always red's bailiwick, but it's definitely in blue's manipulative wheelhouse. It's very self-synergistic, allowing you to tap down an opposing army with those attacks in order to swing freely and grab a bunch of cards the next turn. Certainly both Limited and Constructed playable, and extremely amusing - or annoying, or both - in EDH.
