Damage from your attack is indicated to the right of the attack name
The GW enchantment list has shown the power of Disturbing Katilda, Dawnhart Martyr to generate a huge Flying/Lifelink attack out of nowhere, and the Valkyrie offers a similar level of instant impact without nearly as many hoops to jump through
Even if you are skeptical, I would recommend giving a Unstable draft a try, and maybe stick a few of the cards you draft that amused you in your Commander deck for a little while
This is a remarkably inefficient card from a card-advantage perspective, but being able to counter spells for free is so valuable that Force of Will remains a consideration for many who just dont have mana laying around

But it also means your opponents probably have a slightly better chance of finding some relevant interaction to take down your Descent Into Madness or Contamination token before it completely shuts them out of the game
