Haste Enlist Whenever Goblin Morale Sergeant enlists a nontoken creature, you may conjure a duplicate of that creature into the top five cards of your library at random. The duplicate perpetually gets +1/+0 and gains haste.
{2}, {T}, Pay {R} for each target: Tap any number of random target creatures. Goblins tapped in this way do not untap during their controllers' next untap phases.
When Goblin Recruiter enters the battlefield, search your library for any number of Goblin cards, reveal them, then shuffle and put those cards on top in any order.
Trample Goblin Rock Sled doesn't untap during your untap step if it attacked during your last turn. Goblin Rock Sled can't attack unless defending player controls a Mountain.
{R}{R}, {T}: Target creature you control can't be blocked this turn. Destroy it and Goblin Sappers at end of combat. {R}{R}{R}{R}, {T}: Target creature you control can't be blocked this turn. Destroy it at end of combat.
{1}{R}: Goblin Ski Patrol gets +2/+0 and gains flying. Its controller sacrifices it at the beginning of the next end step. Activate only once and only if you control a snow Mountain.
{R}: Creatures you control gain haste until end of turn. {3}{R}{R}: Create a 5/5 red Dragon Spirit creature token with flying. Activate only if you control an attacking modified creature.
