Hylda's Crown of Winter

At the beginning of your upkeep, if an opponent controls more lands than you, create a Treasure token. (It's an artifact with "T, Sacrifice this token: Add one mana of any color.") 2W: Choose another player. That player gains control of target Treasure you control. You draw a card.

This spell costs 1 less to cast for each creature that attacked this turn. Witchstalker Frenzy deals 5 damage to target creature.

Whenever an Aura you control enters, draw a card.

Menace (This creature can't be blocked except by two or more creatures.)

This spell costs 1 less to cast for each creature that attacked this turn. Draw three cards.

When this enchantment enters, exile up to X target creatures. For each of those cards, its owner may play it for as long as it remains exiled. Whenever one or more nontoken creatures enter, if one or more of them entered from exile or was cast from exile, you draw a card. This ability triggers only once each turn.

First strike Celebration — This creature has double strike as long as two or more nonland permanents entered the battlefield under your control this turn.

At the beginning of your upkeep, put target creature card from a graveyard onto the battlefield under your control.
