For large orders & collections I generally will sleeve/double sleeve all the cards where appropriate, and if some cards are especially valuable will occasionally put the higher value cards inside a cheaper deck box inside that box for an additional layer of protection
It's easy to disrupt, and you do need a creature worth pointing at (big, and ideally with keywords like lifelink or deathtouch)
Target creature you control fights target creature you dont control
If you dont cast it, put it into your hand. Basically, as long as you use instant speed spells, you can constantly generate value by drawing cards or casting stuff for free, and thats really very hard to beat when youre also messing up everyone elses fun at the same time
