Haste Cycle (PLZ HELP)

heres a little deck i threw together today and id love some help developing it. the idea is to play low cost haste spells that sac at eot, and return them to your hand before the sac. i also threw in the siege-gang commanders because those are fun to keep pumpin our gobbies you can sac to deal damage. the renegade doppelganger is is pretty fun to double up on your creature attacks, but they end up getting sacd like the cloned creature would does. you can pump out siege gang commanders all day but youll have to decide if you want to unsummon your ball lightning, or the doppelganger so you can unearth your haste creatures
