I cut [card]Red Suns Zenith[/card] for it and have been very happy, since X-burn spells feel like a necessary evil but are underpowered compared to [card]Lightning Bolt[/card] variants at almost every point in the game

Sample combos[edit] A-to-Z Dragon Buster Cannon "A-to-Z-Dragon Buster Cannon" can be summoned off of just "Union Activation", however the combo to do so is long and requires usage of every card in the Extra Deck, meaning an A-to-Z deck aiming for this needs to be built around the combo
Perhaps "fair" is not the appropriate word for this effect, as there are plenty of ways to use it in an overpowered capacity
You don't need many things triggering off that for it to quickly own a game
