That includes this Ultra Rare version of Rosas Encouragement, but also the Special Illustration Rare version , and second-tier chase Pokmon like SIR Mega Starmie ex
Its drawback may look like its very punishing and can allow the opponent to surprise you via a mid-combat spell, but I never really saw that scenario play out since its damage prevention ability is a a conditional static ability so as long as its on when damage is dealt, it wont be prevented. (Thank you, @fenaris!) It usually plays out somewhat like a colorless Ashenmoor Gouger / Chimeric Idol where you typically dont bother trying to block with it (why am I blocking with my aggro guys anyway?) and, if need be, you cast a spell pre-combat to activate it (typically I used a large coin, like a quarter, to denote whether it was on or off)
Yepsay goodbye to those hard-earned evolutions
Annihilator 2 packs a punch, and often just means whoever got swung in on no longer has an opportunity to win the game
It is not quite as extreme as that, forcing a removal with a three mana card in the early game is fine, especially when they then don't have it
