"The strength of Adeline is the card’s ability to generate a lot of Human tokens via combat, which makes it a terrific commander engine to run a token-based strategy through and because Adeline’s power quickly scales up relative to the number of creatures you control, it also makes her a threat to “one-shot” opponents with commander damage. So, tactically the card does multiple things well with a relatively cheap converted mana cost of three.

One-third land, one-sixth mana ramp spells (approximately 50 percent-plus of the deck is dedicated to smooth, productive mana). The other half of the deck is all dedicated to building synergistic and scaling token pressure (with a bit of interaction and board protection as well).

The general concept of the strategy of this deck is that we want to spend the first three turns of the game developing your mana and ensuring you hit every single land drop for the entire game. It may seem like I’m overboard on the mana here, but the absolute worst thing that can happen for a deck like this is to ever miss a land drop! The budget aspect of the deck also forced me to make some hard choices to ensure consistent and smooth mana production. The budget was tight and I had to make difficult cuts of cards I really like and know would be great in here to ensure I had enough budget to field the best possible, functioning strategy.

Once we get to turn four, the decision tree will start to take shape. One great thing about the deck is the Commander is relatively cheap to cast with a mana value of three, which means it’s always an option. I also would like to have found budget room for a Whispersilk Cloak to make Adeline an unblockable, one-shot threat. "
