The Knight of Commentary

As long as this creature is your commander, you may play cards from any game in your deck as long as they can be reasonably translated into Magic. They all fit within this Commander's color identity.

: Create one resource of any type. (Mana or otherwise.)

The Beleaguered Boxer can't be your Commander unless your deck is 100 cards and originally built out of no more than 36 booster packs, plus basic lands.

When The Beleaguered Boxer enters the battlefield, open a Magic booster pack. Remove up to three cards in your hand or graveyard from your deck permanently. For each card removed this way, add a card from that pack to your hand. Those cards are now permanently part of your deck.

As Rukarumel enters, choose a creature type.

Slivers you control and nontoken creatures you control are the chosen type in addition to their other creature types. The same is true for creature spells you control and creature cards you own that aren't on the battlefield.

, : Create a 1/1 colorless Sliver creature token.

Gen gets +1/+1 for each different year of release among other nontoken permanents you control. (For example, if a card was released in 1993, that's one year of release. Specific editions matter.)

Whenever Gen attacks, if its power is 30 or greater, you win the game.

Horsemanship

The Horizon Seeker gets +1/+1 for each different named keyword and ability word among permanents you control and instant or sorcery cards in your graveyard. (For example, flying, landfall, and scry count. Flavor words, like "Magical Tinkering", or game terms like "enchant creature" and "mana" do not.)

If The Snapstone Wielder is your commander and your deck contains no land cards, your starting hand size is four and for the rest of the game, at the beginning of your upkeep, you get a mana counter. During each of your turns, you can spend mana of any color equal to the number of mana counters you have. (You want mana on opponent's turns, you're on your own. Who needs instant-speed interaction—)

Whenever The Snapstone Wielder enters or attacks, cast a random nonland Magic card without paying its mana cost. If it has targets, choose the targets at random.
