Flying, lifelink
Ward—Sacrifice three nonland permanents.
If a card you didn't control would be put into an opponent's graveyard from anywhere, exile it instead.
During your turn, you may play cards exiled with Valgavoth. If you cast a spell this way, pay life equal to its mana value rather than pay its mana cost.

+1: Draw a card, then add one mana of any color.
−2: Create a 4/4 red Dragon creature token with flying.
−8: Search your library for any number of Dragon creature cards, put them onto the battlefield, then shuffle.

If you control a commander, you may cast this spell without paying its mana cost.
Creatures you control gain indestructible until end of turn.

While it's October 25th, 2024, whenever you cast your commander, create a token that's a copy of it except it isn't legendary.
While it's October 26th or 27th, 2024, if one or more tokens would be created under your control, instead twice that many tokens are created and each of them enters with a +1/+1 counter on it.
On any other date, both abilities apply. (Because why not?)

+2: Look at the top card of target player's library. You may put that card on the bottom of that player's library.
0: Draw three cards, then put two cards from your hand on top of your library in any order.
−1: Return target creature to its owner's hand.
−12: Exile all cards from target player's library, then that player shuffles their hand into their library.

Norman Osborn can't be blocked.
Whenever Norman Osborn deals combat damage to a player, he connives. (Draw a card, then discard a card. If you discarded a nonland card, put a +1/+1 counter on this creature.)
