It doesnt do anything spectacular, but does provide some neat deck-building choices to work around to use effectively
If Alisaie Leveilleur and Alphinaud Leveilleur are your commanders, your deck may contain cards with white and/or blue in their color identity, but not black, red, or green
You also likely wont need as much colored mana in an artifact-heavy deck so utility lands like this arent as big of a risk
As it stands, however, Liliana is probably the better option
The starting stats are bad, but this can quickly grow and it's attack trigger can help aggro decks get in for lots of damage early
Kros deals out shield counters (defense contractor), but there are other options
