Target 1 Warrior-Type monster with 1500 or less ATK; equip this card to that target. Monsters your opponent controls with 1900 or more ATK cannot attack that target.
1. I was referring to original name. Wildheart is English translation https://www.youtube.com/watch?v=6sIR-oNjRH8&t=5s
2. This card affects opponent's monsters, not the monster equipped with this card.
3. It does not work, because Flame Wingman has more then 1500 ATK.
Let say if your opponent play quick-spell "Shrink" on your 3000 ATK Warrior-type monster, and attack it with 1900 or Higher ATK monster, then you activate "Hero Ring", equip to that halved/1500 ATK Warrior-type monster, and prevent it from being destroyed by battle.
"Shrink" last till end of this turn, therefore, your Warrior-type monster's ATK returns to 3000 ATK. And "Hero Ring" still equipped!?
