[L] Static: 30 damage
Usually they will only give you colorless mana, so that is why you dont want to run a lot of them
Meanwhile, Yennett, Cryptic Sovereign is one of the most interesting build-around commanders in the set, facilitating a brand-new archetype in odd-converted-mana-cost tribal (while still being fine on its own, with the double evasion making it pretty easy to draw an extra card each turn if you can't cast that card for free), while Varina, Lich Queen finally unites all of the colors of Zombies, so if you are looking to add the white Amonkhet Zombies to the blue Innistrad Zombies on the traditional black Zombie base, she's the best (and only on-tribe) option for your commander
Her 'The Singing Sword' ability also lets her challenge ready characters whenever you play a song on your turn, so there's basically no escape from her blade
This means that they're going to be a bit slower and less consistent than their budgetless counterparts
Ultimately that's the real fun of TCG, and we're not all losers, regardless: I'm playing a Dragonite deck at the moment, tinkering away with something that feels decidedly old-school and off-meta
