Theme: Legends and Equipment.

Gameplan:  Get to 4 mana and cast Sisay.  If there are no major threats to deal with, fetch Karametra, then use K's built-in ramp and/or Nykthos to fetch and cast progressively bigger & nastier legends.  If there's a must-answer threat on board, get a mid-priced answer instead: Eesha for blocking big creatures, Mageta for wiping out many creatures, Linvala for stopping activated abilities, Glissa for smashing artifacts, Mangara for exiling any one thing.

Strengths:  Sisay has a toolbox of interesting legends to pull from that can handle a variety of situations, and as a repeatable tutor herself, she compensates for the lack of card draw.

Weaknesses:  If Sisay is kept off the board, the deck becomes very inconsistent.
