Gemshe77

Here's my version of a BR Gemshell deck, with a 7's package thrown in.

Something of note- you could replace water elementals and battle toads with the Lore Thief + Gabrian Commander package. That package makes the deck a bit more consistent, however your early game becomes a bit weaker to single-target removal like soul drain and seifer's wrath and you lose out on water elemental's utility in land ramp.

Another note - groundshaker can be replaced with firestorms, it's a meta call, groundshaker is typically good with a lot of small damage pings which this deck doesn't have, however my build has battle toads to help supplement that need.

Potential Additions;
- Lore Thief is a strong consideration
- Crystal Flower is a strong consideration
- Firestorm is a strong consideration, unfortunately it does require 3 mountains though
- Ancient Herald
- Hellfire
- Gabrian Commander
- Seifer, Blood Tyrant
- Seifer's Wrath is really efficient and cheap removal, there's just better options IMO

As a final note gemshell can work in multiple strategies, I consider the "Combat" and "Bargain" builds to be completely different decks though, they have different gameplans and their skeleton builds are very different as well, even if they do sometimes run 7's synergy.
