First Assault mode monster, please critique

[PrometheusMFD]

After the release of Crimson Crisis, I really wanted to make an Assault Mode monster. I did, bu the wording is awkward. Any criticism would be appreciated

 

1 Tuner + 1 or more non Tuner Monsters with 500 or less ATK

The ATK and DEF of this card is the combined ATK and DEF of the cards used to Synchro Summon this card. When this card destroys a Monster by battle, put 1 Counter on this card. When a card is activated that makes this card's controller discard a card(s) from his/her hand, you can remove Counters from this card equal to the number of cards that would be discarded instead.

 

This card cannot be Normal Summoned or Set. This card cannot be Special Summoned except by the effect of "Assault Mode Activate". The ATK and DEF of this card is equal to the ATK and DEF of the "G-Sniper" used to Summon this card + 500. Once per turn, you can place 1 Counter on this card. When a card effect that discards cards from either player's hands activates, you can remove 1 counter from this card to negate the activation and destroy that card, and draw cards equal to the number of total cards that would have been discarded.

I like the effects and the first pic, but the second pic doesn't exactly scream "sniper," really. I'll give you a 9.5, 10 if you find a better pic.

Correct OCG for your Synchro:

1 Tuner + 1 or more non-Tuner Monsters with 500 or less ATK

The ATK and DEF of this card is the combined ATK and DEF of the cards used to Synchro Summon this card. When this card destroys a Monster by battle, put 1 counter on this card. When a card is activated that makes this card's controller discard a card(s) from his/her hand, you can remove Counters from this card equal to the number of cards that would be discarded instead.

 

And read this. Your /Assault Mode monster doesn't fit it.
