Ive been playing burn for a long time, i like trying new cards in my deck because sometimes they're good. And sometimes cards that werent good in the past become better as the meta changes.
I remember when chain lightning was a new card and i ditched all my earthquakes.....
Anyway...
Ive been playing exclusively online the past few years and lately I've been testing out 2 couriers. Ive had mixed results. Sometimes theyre really great. As in sac it and win the game immediately with the cards under it. However, a lot of the time it winds up not working out. I havent kept real results of when it's great and when its terrible, but im not really interested in it anymore, im replacing them with 2 risk factors as soon as i can.
Also....ill agree that burn doesnt NEED card advantage to be successful, but it never hurts. Having extra cards, or the ability to choose your next draw is really helpful with almost every magic deck ive ever played. Make yourself some pretend red brainstorm cards and see if a friend will let you play them....getting a choice of 3 cards for your next draw is super helpful.
Obviously such a card will likely never exist, but some kind of card draw/ selecting would be helpful to me in lots of the games i loose.
Something else ive been trying out are wastelands. Im running 18 mountains and 2 wastelands. Theyve been really helpful. Before i put them in some lands were just auto losses.....glacial chasm, dark depths.... Now theyre not. Its also useful against mishras factories and tabernacles. It sometimes holds off hymn to tourachs for a turn or 2, or takes away stp....
Theres lots of situations where its been helpful.
I mostly consider it a spell to take out trouble some lands, but its mana producing ability isnt wasted either. Some of our spells do take colorless mana, pop and all of the 3cc spells i use do. It also pays for daze and thalia....
Every card has ups and downs....and i know it doesny play great with pop, but i can decide when and how to use it before i cast the pop.
And sure there have been times that ive needed a mountain and got a wasteland instead, but what can you do? Sometimes Ive needed a mountain and drawn a lightning bolt too.
Overall ive been happy with the wastelands.
Looking forward to hearing your thoughts.
