I personally play a minimum of 6 cards and a rough maximum of 10, with the caveat that commanders like Lord Windgrace are going to require more than commanders like Kinnan, Bonder Prodigy
It has a good collection of keywords, but a 2/2 for 3 mana is far too small to be able to take full advantage of them
Budget Alternatives That Still Compete Still considering options before committing to some of the more expensive staples
If a player would draw their second card in a turn, you get to draw as well, and then if a player casts a second spell, you make a 2/2 Knight token
Youd have to be crazy to print that with no downsides, but red has you covered with the trifecta of Final Fortune, Last Chance, and Warrior's Oath, which are functionally the same card (though Last Chance has the superior art with that borderless reprint in Dominaria Remastered )
