Concord — As long as there are four or more card types among permanents you control, you may cast the first spell you cast each turn without paying its mana cost.

When Blessing of Roya enters or whenever you cast a spell from a graveyard, you gain 5 life and you mill five cards. Then you may put a card from your graveyard on the bottom of your library.

When Shambling Gutless enters, target player discards a card.

Whenever you make first contact, create a Treasure token. (You make first contact the first time each turn you cast a spell with a name not in your graveyard or control already.)
{T}, Return an artifact with mana value X you control to its owner's hand: You may cast a spell with mana value X plus 1 or less and with a different name from your hand without paying its mana cost.

Whenever a creature or planeswalker enters under an opponent's control, sacrifice Rune-Scribe's Trap unless you pay {R}. If you sacrifice it, it deals 6 damage to that permanent.

{2/G}, {T}, Sacrifice Globule of Vigor: Draw a card.
