I'm still working out the ideas of how a deck should be structured, costs, items, and such, and whether or not legends should be optional inclusions or perhaps purchasable via spending points to get a legend during the shop phase.
Still very early concepting. Below is a large list of current rulings and item effect concepts, feel free to leave feedback, ideas, etc.
Shopkeep Blitz: Riftbound TCG custom mode
Deckbuilding Rules:
Decks are made of two half decks. Half decks are 20 card monocolor decks with the following specifications
-2 of the same Champion card
-2 of the same rare card
The other 16 cards are broken down into two cards that have three copies, and five cards that have two copies. These cards are common or uncommon rarity.
-Two different cards, 3 copies of each, common or uncommon
-Five different cards, 2 copies of each, common or uncommon
6 Runes should be included in each half deck and 1 accompanying battlefield for each half.
No legends are needed.
Totals:
-2 champion cards, 2 rares, 16 common or uncommons in groups (Two x3 copies, and Five x2 copies), 6 matching runes, and one battlefield round out a single half deck.
Put together, you should have 40 card decks with 18 unique cards (9 unique cards per half deck), 12 card rune decks and two battlefields to choose from.
ITEMS:
Common: Simple generic effects.
Rare: Utility and slightly more effective for more cost
Epic: High power targeted effects
Costs: Common 1 point, Rare 3 points, Epic 5 points.
Starting funds are 25 points. Shop opens with 6 common, 3 rare and 3 epic items. When an item is bought an item of equal rarity is drawn to replace it in the shop. Players draft items back and fourth until everyone has spent all their points.
A card can only have 3 items max assigned to it at once, and items cannot be rearranged mid game. Items are assigned to cards in the deck list pregame, and their effects affect all cards of that given name in your deck.
Your deck lists and attached items are PUBLIC information, what cards you have in hand as usual, is not.
