AST Card Variety and possible card upgrades

[Jallun]

I don't think it needs to be said I'm not the only one who thinks every card being a "mini-balance" is dull, and I initially thought of a few new things they could do that goes as close to the lore as possible:

Bole (the tree): Basically gives the target 5 stacks of Bole, lasting up to 15 seconds, that consumes a stack to reflect an incoming attack* at 300 potency.
Arrow (the arrow): In addition to returning the attack/spell speed buff, adds an extra effect to attacks* that will inflict a 5% physical vunerability up debuff that stacks up to 3 times (2 times on bosses), all effects lasting 15 seconds.
Spire (the sun?): Absorbs damage equal to 10% of the target's HP (if Nocturnal) or grants a 80 potency HoT (if Diurnal) for 15 seconds. If the effect expires in any way, adds 2% damage buff to all nearby allies, lasting 6 seconds.
Ewer (the pool?): Adds a 15-second buff that makes attacks* inflict a 5% magical vunerability up debuff that stacks up to 3 times (2 times on bosses), lasting 15 seconds. When it expires, spreads to all nearby allies that regenerates MP at 20 potency, lasting 9 seconds.
Balance (the gear): +5% Damage/Healing Dealt buff and a +5% damage recieved debuff lasting a total of 20 seconds.
Spear (the flake): +10% direct hit chance buff and direct hits additionally reset the duration, lasting 15 seconds initially and cannot last more than 45 seconds total.

*DoT effects do not count as "attacks"

On a personal note, the seals not being added out of combat makes sense but these cards could, at the very least, switch things up while still providing rDPS in some capacity.
