Brinelin, the Moon Kraken

Brinelin, the Moon Kraken was released in the Commander Masters set in 2023, serving as a reprint that reinforces the creature's role as a staple in Blue-aligned Commander decks. The card was originally introduced in the Commander Legends set, designed to leverage the 'Partner' mechanic which allows players to pair two legendary creatures to lead their deck. Mechanically, Brinelin is built around high-mana-value spells, rewarding players for casting large threats by bouncing smaller permanents back to their owner's hands.

The visual design of Brinelin was illustrated by artist Wisnu Tan, who rendered the creature as a towering, ethereal cephalopod submerged in deep, lunar-tinted waters. The art direction emphasizes the Kraken's massive scale and mystical presence, aiming to evoke a sense of awe fitting for a card that shifts the battlefield state upon entry. Upon its introduction, the card was well-received by the Commander community for its utility as a tempo-control engine in slower, spell-heavy archetypes.
