Forget madness
Leaping into the fray whenever she attacked, Ragavan made up for his 2/1 stats with his fierce reliability: hed show up every turn, without fail, even if he fell in combat the turn before
The great thing is, even if you get this late, you can get some value by at least giving your board lifelink assuming you have poisoned your opponent a bit
For example, if you discover 4 and reveal Galvanic Giant (an adventurer card from Wilds of Eldraine with a mana value of 4), you could cast Galvanic Giant, but not Storm Reading (its Adventure, which has a mana value of 7)
First Strike and Vigilance are both very useful keywords to gain access to, and she can even give them to herself, so her three mana 2/4 body combined with that is a nice deal
