Casting a Conflagrate almost entirely through Delve mana is a new line this card enables for the deck, to give just one example
You can cast it as Coil and Catch for an instant-speed spell that draws three cards and discards one, and then Marang River Regent shuffles back for more potential casts just like the aforementioned Green Sun's Zenith cycle
Since its a may ability, you can decide just how many Wolf tokens you want to make, but keep in mind that each Wolf will force you to draw a card when you attack with Voja, since Vojas trigger is not a may ability
The cost is a big one, five mana is a lot
Casting a Loyal Warhound means that your Knight of the White Orchid is far less likely to ramp for you
Leviathans tend to be massive battlecruisers: They have high power, high toughness, and/or big mana values in addition to imposing abilities like mass bounce or mass tap that your opponents must answer or else theyll lose the game
