Claudio has a few key moves that work well together, allowing great mix ups and tech traps
Claudio's best move is WR2 or Forward, Forward, Forward 2. Also known as "The super man Punch" this is one of the best approach tools in the game. It has great damage, and is used as a common combo finisher, using either the standard version or the Instant version. Apart from dealing great damage it also grants Claudio his Starburst (We'll go over Starburst tools later on). Be wary tho, it is a high so it can easily be ducked and launched if you get too predictable with this move. Be ready to mix this up with Mid moves such as Forward Forward 4 or forward forward 1+2. Forward 4 allows for Okizeme such as sidestep 4 or downback 3. And forward forward 1+2 grants starburst, but due to the starburst animation does not allow Okizeme.
Claudio's best launchers are his infamous "DAH", the hopkick and down forward 1, 2. The hopkick cannot be launch punished and has excellent range for tech traps. Some great tech traps are WR2 on block, forward 3, back 1 and starburst down 1,2. This are excellent on block, granting + frames to Claudio. Button heavy opponents will fall right into a hopkick. Down forward 1,2 doesn't allow Claudio to have a generic down forward 1. It's 15 frames and a natural combo on hit, but is Launch punishable. This are both mids, being able to launch ducking opponents.
