The quicker you can remove resources in a combat-focused deck, the better
Ardent Plea Some Voltron decks might like Ardent Plea as a pump spell that casts an extra spell, but it wont have much use in other decks
It lets you use all your mana turn 2 if you have another 1-drop, it can attack for 2 damage on turn 2, and it gives you a mana sink to mitigate flood and just stress your opponents removal as a 1-drop that will win the game given enough time
It has a big enough butt to survive an Hour of Devastation, for starters
For example, if the player attacking you attacked with a creature with myriad and the tokens created by that ability are still on the battlefield attacking all of that player's other opponents when Suppressor Skyguard's last ability tries to resolve , the condition will no longer be true, the ability won't resolve, and damage won't be prevented
