Tana vs Nina4 - Smash.
Tana vs Elmdor - EDIT: Right, 70 Brave. EDIT: Right, Blade Grasp doesn't catch the double and Tana 2HKOs him.
Tana vs Zero - More smashing. Zero laps Tana once after he morphs, but her evade is so stupid he can't really kill her, and she shaves off 80% PC HP off Zero's health off the cusp.
Tana vs Renee - Renee probably loses regardless of the stance I take on Azureflame Mana needing to be killed to end her fight or not. The evade is just murder on her.
Nina4 vs Elmdor - Status-immune healer mage against Elmdor. That's sad.
Nina4 vs. Zero - Zero against a healer that isn't an evade/pdur god.
Nina4 vs Renee - Weird. Nina is a lot faster, but she can't kill Renee in those three magical turns (doesn't 4HKO - hell, she doesn't even 4HKO average <_<), at which point the pressure from the charge+Mana causes ugly, ugly things. And Renee probably OHKOs with the charge attack as is discounting evade.
Elmdor vs Zero - Thinking Zero's hits get by enough, and I doubt I see Calamity Arts eating Blade Grasp anyway.
Elmdor vs Renee - Charge-OHKOs, same thing as Zero for me. EDIT: Alternatively, summoning the Mana and then proceeding to blast with boosted bombs+Mana magic works just as well.
Zero vs Renee - For now, let's assume Renee doesn't get the privilege of Mana ending her fights after she's dead. Renee goes first, but gets lapped, and... Zero needs to see a third turn to kill. Thankfully, Renee's charge move doesn't OHKO him, and summoning the Mana is a waste of time here. Thus, Zero gets to unleash hell on earth against her. Not bad, though.
Weird that Renee gets more wins than Nina4 in a Heavy pool, but there are a lot of healer killers in this field, and Renee herself qualifies decently as one.
