TF rework idea

Hi everyone. I have taken a liking to TF, but I wish his gameplay wasn't as linear. Here are my thoughts for a rework. Note that I haven't thought about numbers, just general mechanic changes. I doubt these will actually be added into the game but I like the card-throwing mechanics and sleazy lore and wish there was more of a 'gambling' feel to TF. What do you guys think?

A side note: if something is marked in square brackets, I am not sure if it is too strong to be permissible.

1. New W card, which deals low damage, but makes a target take increased damage from all sources for a time. Hitting the same target with an another card or Q (not a regular autoattack) deals extra damage, grants MS for a few seconds, and reduces the cooldown on W [and Q] by (somewhere between 1 and 3) seconds (does not stack if multiple marked enemies are damaged with one ability).
2. New R passive: After using Q or W, TF instantly readies a random card (not necessarily the mark card). W now readies an extra random card, which can be used after the picked card is thrown.
3. New mechanic: up to 3 cards can be readied at a time, and the most recently-readied card is thrown on TF's next auto.
4. New R mechanic: When activated, all enemy champions are marked.
5. Gold card stun reduced by 50%, but stun duration is doubled on marked targets (effectively giving gold card the same stun duration as before).
6. Landing an E-empowered auto on a champion instantly readies a random card.
7. Hitting a marked enemy with a second mark card [heavily] damages them. All enemies near the target take reduced damage [and are marked].
