Several of the invitational cards would go onto much acclaim, but sadly a few would disappear into obscurity and not see much tournament play
First, the champion, playing Mono-Black Necro Control: Creatures (7) Lands (23) Spells (30) 4 Nevinyrral's Disk 1 Hymn to Tourach 4 Necropotence 1 Ivory Tower 4 Dark Ritual 4 Drain Life 3 Stupor 2 Mind Warp 3 Contagion 1 Serrated Arrows 2 Demonic Consultation 1 Zuran Orb Sideboard Then, in third place, representing the aggro decks of the format, Brian Hackers Bad Moon Necro: Creatures (19) Lands (21) Spells (20) And then finally carrying on the fine tradition of B/r Necro-decks, Chris Pikula, who actually increased the red presence in the deck with Incinerates and multiple maindeck Shatters (Winter Orb, Howling Mine, Serrated Arrows, even Black Vise, Ivory Tower, and Zuran Orb were worthy targets)
The goal is to get a few counters in play, then proliferate them and increase them
It is a one-mana legendary monkey pirate creature at 2/2 that, when it deals combat damage to an opposing player, creates a treasure token and exiles the top card of the defending player's library, and you can cast that card until the end of the turn
My personal favourite is a toss-up between Miku, the Renowned by Yuko Shimizu, and Harmonize by Syutsuri, but I wouldn't turn my nose up at any of the other four cards on offer
It's still pretty effective in Commander though, where it can downgrade a huge problem, or take a commander mostly out of commission
