Hyalopterous Lemure is a pretty fun card for the story behind its creation
Its Bloodthirst ability lets it come in with +1/+1 counters based on damage dealt to your opponents, and its Enrage effect lets it deal damage to an opponent, each time it takes a hit, unless they sacrifice a (non-token) creature
A different build would be focused on blink and creatures that have good enter the battlefield effects and higher toughness than power, like Sea Gate Oracle, Brago, King Eternal, and Wall of Omens / Wall of Blossoms
It clears aside a problematic blocker and potentially enables a team-wide swing with protection
Reckless Rage is a four-of in the deck and isn't especially replaceable since it offers not only incredibly efficient removal, but another way to target your own creatures with a spell to grow heroic threats like Favored Hoplite and Tenth District Legionnaire
