yugioh destroy spell card Cursed Seal of the Forbidden [DR2-EN049] Common All cards will be carefully packed for safe transit Flash of the Forbidden Spell

Lands are colorless unless stated otherwise

Well, they havehundreds of times in fact

Even if you dont win, just participating can earn you rewards such as booster packs or rare cards

The three life you gain rarely makes much odds however and on that basis incinerate is the better card (despite helix being less playable in general anyway due to more restrictive colour requirements)

Both have a lot of mythics that were hyped for casual and Commander play but not obviously great for Standard (these are the Gods for Hour of Devastation and the Dragonlords for Dragons of Tarkir ), both are sets without a rare land cycle, and both are the final sets in their respective blocks
