FREE: MtG Oversized Ertai "Character" card from Vanguard Magic the Gathering pretty rare

It's an old variant where you got a "Character" to use. From wikipedia:

Vanguard

In this variant, each player has a special card that affects the game. These cards change the players' starting life total and cards in hand, and have additional effects as well. Vanguard initially began with special oversized Vanguard cards, released as part of various promotions.[51] Only four sets of avatar cards were made before the product was discontinued. The cards featured depicted major characters from the storyline of Magic, including Gerrard Capashen, Karn and Squee. A new version of Vanguard was eventually added to Magic Online, with a player's avatar filling the role of the oversized physical cards.[52] Players are given a standard set of avatars and can receive more as entry and high-finishing prizes in release events.[53] New avatars are regularly added as new sets of Magic cards are released, each depicting a card from the set.[54] The wider availability online, combined with occasional tournaments, has made online Vanguard more of a success than its physical predecessor.

One recent addition to the regular Vanguard format is Momir Basic, which involves the Momir Avatar, which allows a player to discard a land card to get a random creature into play. All Momir Basic Decks are constructed entirely of basic land.

Yeah, I guess it is sort of
