wanton stag
Hey guys, I would like some deck-building advice for an event I am being a part of.
The LGS where I volunteer is planning an archenemy-styled event aimed at newcomers and younger players and they wanted me and some others to make some Voltron-esque decks to act as 'Raid Bosses' for the players to fight against (We all would be assigned a separate table that players will bounce around). The only deckbuilding rules was to not make anything too close to Cedh, as it this more a social event rather than a heavier competitive event.
I chose the new Koma and thought I would use minimal creatures outside the big boy himself and build the rest of the deck around mana ramp and evasion/negation and power buffs, to give the feel that Koma is the big main threat on the board with some cards like his former version to act as stage 2 or a difficulty slider. This is what I have so far and would appreciate the feedback for it or any suggestions.
Thank you in Advance,

less to cast for each card you own in exile and in your graveyard that's an instant card, a sorcery card, or a card that has an Adventure.
