Star-Lord Guards the Galaxy

Element Gun allows this Star-Lord deck to run three copies each of Desperate Defense, Expert Defense, and Never Back Down. Each turn where people don't need the extra block, you could hold onto one, but if you're really flooded, you can just use them to fire your two Element Gun and deal an extra 6 damage across 1 or 2 targets. One great aspect of them not to overlook is that their attacks have piecing.
