The legend rule has long been a basic tenet of Magic
Most moves deal damage, but as you can see, Charge does not do any damage
And the most important and final point, which will accurately determine both yours and the fate of the card, is the inscription " 1st Edition "
That card is always a 3/1 flyer that can only block flyers, but thats a pretty good impression of Repulse if you ask me
That means if your foe doesnt play a creature or have any way of stopping your attack, you can attack and deal 11 damage to your opponent, then sacrifice the Scamp immediately to deal them another 11 damage ending the game on the spot
Furthermore, its second attack, Sonic Blast, is able to deal an immense 220 damage , making it able to knock out multiple other ex cards in a single hit
