Obviously, The Writhing Township is a lot to be excited about. A 7/4 with trample and haste, after all, is nothing to sneeze at. But it gets better. Whenever, The Writhing Township attacks, it brings along two 3/2 Eldrazi Horror tokens onto the battlefield tapped and attacking. It’s like a super Hero of Bladehold, and that card was a monster in its Standard days - and even still sees play in Modern. There is precedent for this type of card to be good.
How do we meld them into a Writhing Township? There’s a 5 mana ability on Hanweir Battlements that you can activate if you control a copy of Hanweir Garrison. You then exile both cards and put the Writhing Township into play.
Both cards appear to be playable on their own, which is definitely a plus. Hanweir, the Writhing Township looks to be an absolute game-ending bomb. This is definitely a Meld card to be excited about. The fact that both pieces of it could work in an aggro deck already means we could definitely see this combo see Standard play.
