For Round 1 :
I suppose the shards that are upgraded count in normal ups limit?
If my deck cannot be exactly cut into 1/2 1/2 (or 2/5, 2/5, 1/5) (example : 31 cards), what are the rules?
Spells take action before duels but after deckbuilding?
what is the (n) next to each spell name?
1. No, the shards do not count towards your upgraded card limit.
2. Get as close as possible to the required proportions. Of course, that only counts if your deck cannot be perfectly divided.
3. Yes, spells happen before duels but after deckbuilding. At anytime time during that period. There will be a public topic for spellcasting that all will post in if they cast a spell.
4. That is how many times a Prefect can select that spell to be given out. if a spell has (3) that means that spell can be given out three times.
I suppose the shards that are upgraded count in normal ups limit?
I also suppose Shards are considered to be in-element? Not other...
Anytime other cards are allowed they will count as 'In-Element'. So, for example, a deck with 15 Fire cards, 13 gravity cards, and 2 other cards is a legal deck.
