When a Masters set has a high expected value, it's a lot easier to justify spending $45 on a booster draft or $200 on a booster box because even though the up-front cost is high, you know that you'll get some of that money back in the form of cards you can use to build decks or, if you don't get the specific cards you need, trade or sell to get the cards you do need for your decks
I guess that flanking might be a fixed version of rampage
After all, many red removal spells and creatures only cost a single red anyways
To truly succeed, it needs a professional execution
If the table votes duplication for whatever reason, you get to counter that spell anyways because youll copy the counterspell and aim it at the original
These are typically used for mass distribution, especially with media
