Ob Nixilis, Unshackled

Flying When this creature enters, if your life total is less than your starting life total, it becomes equal to your starting life total.

Whenever you draw a card, put a +1/+1 counter on this creature. When this creature dies, create X 1/1 blue Squid creature tokens with islandwalk, where X is the number of +1/+1 counters on this creature. (They can't be blocked as long as defending player controls an Island.)

Artifact spells you cast have convoke. (Your creatures can help cast those spells. Each creature you tap while casting an artifact spell pays for 1 or one mana of that creature's color.)

You may have this creature enter as a copy of a creature you control, except it has "2UU: Return this creature to its owner's hand."

Destroy all creatures you don't control and all planeswalkers you don't control.

Destroy all creatures you don't control and all planeswalkers you don't control.

Flying At the beginning of your upkeep, draw a card unless target opponent sacrifices a creature of their choice or pays 3 life.

Other Goblin creatures you control attack each combat if able. At the beginning of combat on your turn, create a 1/1 red Goblin creature token with haste. Whenever this creature attacks, it gets +1/+0 until end of turn for each other attacking Goblin.
