Eowyn is a Token generating machine with her first triggered ability but apart from her there are also 10 other cards that make tokens
It's an unusual mana dork, asking you to put -0/-1 counters on it to get mana instead of tapping it, which means it can both make mana and block small creatures
Whichever ones you get in your opening hand should have a big influence over how you play the match
[5] The classic example is something like, If I let you resolve your commander will you agree to not counter mine next turn? Basically, both of you get something out of it
The other option is to take advantage of the direct damage, which is good in its own right to either finish off a damaged character or get them within range to be banished but also works with the likes of cards that benefit from being damaged - such as Scroop, Backstabber - that benefit from healing damage, like Rapunzel, Gifted Artist, or from damage being dealt: like Beast, Relentless.
Running cards like Slither Blade, Triton Shorestalker, and Mist-Cloaked Herald guarantees you a ton of card draw, as they can easily slip past and deal combat damage
