Dont want your opponents casting all sorts of game-winning spells
The Collectors Market Boom When the OPTCG launched, many assumed it would only serve as a casual card game
Here is the list: Battle at the Bridge Borborygmos Enraged Encroaching Wastes Kazuuls Toll Collector Magmatic Insight Nissas Defeat Rakdos Charm Roast Sanctum of Ugin Triton Shorestalker Warping Wail Some of these cards, like Rakdos Charm and Nissas Defeat, are sideboard cards that rarely make an appearance in Pioneer at the moment but easily could in the future if major metagame shifts come about
Sometimes a quick way to victory is using Nicol Bolas, Dragon-God to mimc the +2 or +3 abilities from other planeswalkers, including your opponents, and reach the ultimate quickly
From things like Myr Battlesphere to Noxious Gearhulk, these artifact creatures come with all kinds of unique abilities and mechanics that make for interesting gameplay
