And with an ended poll, we are tied. This means it's time for me to come in (anyone with the authority can confirm I did not vote) to break the tie.
Both of these cards are reasonably flawed, as makes sense for such a tough criteria. I actually think they're pretty interesting, and show a sort of contrast.
Shadow Tether is a very solid card. It's a nasty way to soft-remove creatures, and is very cheap for a jumping Pacifism equivalent which makes sense when you can grin and bear it, making it better when its controller is ahead. The card is a solid workhorse at what it does without being really over the bar. However, I feel that the prompt got more lost here. Is there any reason why this couldn't be an Equipment with the Bind keyword? Equip innately cares about who controls the creature... but Equipment, as a type, does not. Hence why we can get
Bloodthirsty Blade as a design. Keywording the "equip to an enemy" ability as "Bind" would be pretty cool and have design space, but I think it would just stay equipment, since there's no inherent difference.
On the other hand, a Blessing is at least different from an Equipment or Aura... but dang Echo is slow. It takes two turns from casting this thing to being able to use it no matter what phase of the game you're in, since you have to wait to upkeep and *then* tap a creature to pick up the blessing, meaning you then have to untap with the blessed creature to get any use out of it. And should you need to rebless, it forces a downtime turn again. I feel like this could have cost
and still been weak (but not unplayable) because of how absolutely glacial it is. Yes, 2 to cast/2 to equip is pretty standard for Flying and a positive rider on equipment but that can still go live the turn after you play it on curve or same-turn later in the game, and can go live again on your very next turn after your creature gets shot down rather than having a null turn every time. But I feel like the
idea of the blessing type has potential. Some of the details might need to be adjusted to give it design space that isn't very sad. Like perhaps it should bless unblessed creatures rather than attaching when unattached (changing the dynamic so each creature can hold one and one can be held by any number) or be as-is but bless as a sorcery rather than on upkeep to shave a turn off the initial start-up. But can I judge the card on its potential if it were workshopped? No, but the fact is still true that Blessing
is a new (sub)type in a way that Shackle fundamentally isn't. This card better respected and executed the criteria even if I think the card is absolute pack-filler.
And I think this is part of why this contest has been so tough. Not only do you have the choice between a solid workhorse and a janky but conceptually exciting card, but you have to decide between having the better-executed card and having the better evocation of the prompt.
In the end... I think I have to give the nod here to Razor. I love what Tether is doing as a card, and will be dropping it into CotW as something of a consolation, but its prompt treatment is like typing "creature with flash" to "summon" -- the Rubric these cards are being graded on is skewed so hard in favor of Blessing that it ultimately does tip the scale.
WINNER: RAZORBORNE
