the reverse, max 25 ups. so 39 card deck is 23 ups, 35 is 15 ups, 30 is 5 ups.
This is correct.
If I understood it right, if you use 4 shards total you can't add more than one copy of any other card (except pillars, etc.), so you'd also need the 4 shards to be different for the deck to be legal.
If you use four shards, you are only allowed one copy of every different card which you use (aside from elemental pillars and stuff) So even your four shard would have to be in different elements, because you wouldn't be allowed more than one copy of each different card (and shard is a card as well)
So to build a reasonable deck, two shards is probably the relative maximum. (Since that would still allow you to play three of each different card in your deck.
--> At least that is my interpretation.
yes, you can't have 3 of the same shard. You can still put 2 of one kind and one of a different one.
These are all correct. If you have four shards in your deck, your copy limit is one, so all four shards must be different. If you have three shards in your deck, your copy limit is two, so you can either have one copy of Shard A and two copies of Shard B, or a single copy each of Shard A, B, and C.
Does that correctly list all valid configurations for including shards ?
As far as I can tell, yes, it does.
QP is a pillar so I am guessing it will be unlimited
This is incorrect. The rules state
elemental pillars/pends/towers/marks, excluding Quantum Pillar/Tower. As such, QP/QT is subject to the copy limit based off the number of copies of shards in your deck.
Question to TO: Are these decks legal?
All three of these decks are illegal. The first and second decks have too many Quantum Pillars/Towers. The second deck also has too many copies of Skeleton, Arsenic, and Relic for the number of copies of shards in the deck. The third deck is illegal because it has one too many copies of Dune Scorpion - with zero shards, the copy limit is five, not the game's default of six.
Anything more?
