Just was looking at these cards and saw a possible combo and just wanted to make sure the timing would work. Basically, play a throw and make sure it deals 5 or more damage. Use Marius' R to retrieve Ready to Launch from your discard pile, and play Ready to Launch to play a throw. If my understanding is correct, this could work as you choose the order that responses are played in. If someone more familiar with the rules could confirm or deny this, that would be great!

Marius Gaius

R: After your attack deals 5 or more damage to your opponent, take 1 action card from your discard pile and add it to your hand.

Ready to Launch

R: After your throw attack deals damage, take 1 throw attack with printed difficulty less than the damage dealt from your discard pile, and add it to your hand. Discard this card from your card pool.

the both trigger when your attack deals damage so you could do both

Yeah, that works. you can fetch RTL and then play it.

Awesome! Thanks!
