It's for classics convoy. Classics magnus is this one: TAW-01S TAW God Sword - Classics Magnus Version - Transformers Classics Accessories
I almost bought the Prime and Magnus ones when they were clearance for $62.99 and then another 20% off on sale. Still didn't bite (I wish I had). Definitely not for $79.99...
I got the "Nemesis" one on the first run, because it's the PERFECT anime-style Headmasters Master Sword, the break-down into a small-hand-held-blade, or build-up-into-a-huge-weapon play pattern works so nicely to recreate Fortress's use of the Master Blade in the anime. Now, my cast of Headmaster characters in the 'Classics" collection to USE said sword is rather light, but Stronghold will definitely be getting it now D/L
