Quote from RatolyExcept they both have different uses. My prediction is simple: A lot of the newly printed cards are bad at first sight, but turn out to have plenty of combo potential. While my personal favorite is Quest for Ula's Temple, I can easily see its green and red counterparts being played. And while Wrexial is not quite as great as Jwar-Jwar, at U (<- link) he's a lot better.

Terastodon is easily chump blocked? You've got a 9/9 and three 3/3s. How are they chumping that? If there's a reason that it's dubious in limited, it's because many games are decided by the time you can drop nine mana. Not because four creatures is somehow easier to block than one.
