how many cards are in a standard mtg deck Week One Kaldheim Decks Black deck of 100 Magic cardswith 1 foil Arena Black/Red // Standard deck

The fact that its also basically a lord that buffs all of your heroes and artifact creatures is a sweet bonus, and sometimes it might even give an absurd +3/+3

You dont really need to give your board more than three +1/+1 counters before it starts becoming a serious threat

A board of unassuming 1/1 mana dorks suddenly becomes a lethal army

Dryad of the Ilysian Grove is a strong second since it fixes your mana and makes it easy to activate Sisays ability

In a blog post, Wizards gave the example of Omnath, Locus of Creation, a previously banned card that will be reintroduced with an additional mana cost and an altered ability (it will now let you scry one card instead of drawing a card)

Thassas Oracle might be a controversial card in many situations, but I think even its harshest critics would agree its a fair inclusion here
