Goblin Barrage — ruling 1

If you put a permanent with a kicker ability onto the battlefield without casting it, you can't kick it.

Goblin Barrage — ruling 2

If a spell's kicker cost was paid, the spell is "kicked."

Goblin Barrage — ruling 3

The kicker ability doesn't let you pay a kicker cost more than once.

Goblin Barrage — ruling 4

To determine a spell's total cost, start with the mana cost (or an alternative cost if another card's effect allows you to pay one instead), add any cost increases (such as kicker), then apply any cost reductions. The spell's mana value remains unchanged, no matter what the total cost to cast it was.

Goblin Barrage — ruling 5

If you copy a kicked spell on the stack, the copy is also kicked. If the copied spell is a permanent spell, the token the copy of that spell becomes when it enters is also kicked.

Goblin Barrage — ruling 6

If a card or token enters as a copy of a permanent, the new permanent isn't kicked, even if the original was.

Goblin Barrage — ruling 7

You can't cast Goblin Barrage unless you choose a creature as a target, even if it's kicked. However, you can target a Goblin or artifact creature you control and then sacrifice it to pay the kicker cost. The target player or planeswalker will be dealt 4 damage.
