Forum:Gyzarus Vs Prime Material Vs War Chariot

If I negate Gyzarus's effect to destroy 2 of my monsters with Primes effect, and he then use's War Chariot to negate and destroy my prime... Can I use Prime again to negate the War Chariot (I have cards in hand to do this)?

My Understanding is that as long as the effect is to destroy a monster I can negate the effect and can activate primes effect as many times as I have cards in hand.

Was I right or wrong in this assumption??

(Needless to say I allowed the chariot to destroy my prime and lost the match, seems as he started sulking and crying i was a cheat :
