I'm glad you are not balancing the game. I'm sorry but these are hot garbage and don't make sense.

Giving a good effect on top of the card effect is not "improving" a card, it's lazy and in a consistency viewpoint it doesn't make sense, aside from flooding the card text.
Temporus acting as a self full heal on top of it's effect is dumb, doesn't fit with the card and it's just a lazy and unengaging way of buffing a card
Toki being a 0 5/5 on turn 1 it's not fun to deal with, aside from being stupidly unbalanced (and losing your 5th turn is NOT a good consequence of having her in your deck).
Hallazeal has +2 spell damage on top of his effect, again, adding a good effect on top of the other effect is lazy and not a real buff, besides the card doesn't even need a buff.

The rest are just again, other words on top of their normal effect, but even with these buffs these cards would still see NO play, none of these changes are good enough and don't even fit an archetype, cards are put in your deck for synergies or powerful effects, these don't fit any

The one card i do like is Cho'Gall, but even with that effect it still would not see play, too expensive for the cost and warlock is not known for having expensive spells to use, aside from the card also being powercreeped by Bloodbloom, which was nerfed for breaking wild
