Haste (This creature can attack and {T} as soon as it comes under your control.) Other Goblin creatures you control get +1/+1 and have haste.

Echo {1}{R} (At the beginning of your upkeep, if this came under your control since the beginning of your last upkeep, sacrifice it unless you pay its echo cost.) When this creature enters or dies, create a 1/1 red Goblin creature token.

Battle cry (Whenever this creature attacks, each other attacking creature gets +1/+0 until end of turn.) This creature can't be blocked except by creatures with flying or reach.
