While Heart-Piercer Bow was also printed in Fate Reforged at the same time as Renowned Weaponsmith itself, there was no such card in the game called Vial of Dragonfire
The blue flames of Charizards Dragon-type Mega X form, contrasted with the red Japanese text, translated as Inferno X - this cards signature move
It never featured in any starter decks for Rise of the Floodborn or later sets, however, so acquiring copies of the card was still a luck of the draw situation
The card sees plenty of play in EDH, though its very risky to keep losing life from your land in 20-life formats
Dialga, Palkia, and Giratina share similar designs to this card, though Arceus places second among the four, with Giratina ahead
It does a lot, though, and doesnt just trigger when it attacks
