I think i found a solution for SE to let us upgrade the TT deck.

[Nari-Tia]

Main reason for SE for not letting us upgrade our deck (at least i think), because then they have to rewamp all the existing NPC-s, and it would ruin the balance between new and old players.

BUT i think i found a solution.

We need a new rule to npc's and for pvp that can syncronize with the card restrictions and the card counts.

There should be a new rule, called: deck restriction. Sounds weird. But it should look like this:

"Deck Restriction: Rank 1" - wich means you can only use rank 1 restriction cards, when you had less cards back in the game, if you remember: 1x ★★ or higher + 4x ★.

"Deck Restriction: Rank 2" - which means you can only use rank 2 restriction cards against this opponent: 1x ★★★ or higher + 4x ★★ or lower.

"Deck Restriction: Rank 3" - which is the currently highest restriction you used to have: 1x ★★★★ or higher + 4x ★★★ or lower.

"Deck Restriction: Rank 4" - which should be the next level tier: 1x ★★★★★ + 4x ★★★★ or lower.

Most of this is already in the game if you have less cards, but now the game could force you to use these kind of restritcions against certain NPC's, or low level players.

So in order to use this system, the game has to ask you when you don't have a deck for this rule, that make a new deck OR use automatic deck building for that match.

Older NPC's should have rank 3 rules or lower so players that unlocked the next tier won't feel too strong against them.

Playing against a new player who has less cards and is in a lower tier you can't put a rule that allows higher tier card restriction. Except in tournaments.
