As far as creature-lands go, becoming an 8/8 for three mana isnt a bad rate, but with no evasion or other relevant combat abilities, you kind of have to really pick your spots for this
TCG is one of the most profitable card games around, generating almost $10 billion and counting since its inception
As one popular simulator notes, "The simulator tries to match the chances of getting certain cards to real-life packs, but it can't promise they will be exactly the same." Think of it as a highly educated guessone that gets you incredibly close to the real thing but can't account for every variable in a physical print run
Ever since, many sets have included a reprint or three and used those cards to sell the set (or, in the case of Planar Chaos , used a side-print of Wrath of God as Damnation to sell the set)
It can fill any party slot and will let you pay X mana to give all your creatures all creature types and become base X/X creatures
However you do it you have to have a good plan going on, which piques my interest
