At 30 cards, there's a 1/6 chance of Ajani being in the top 5 cards.
I'd really just not take the risk since I'd probably be really angry if it really did mill it, and will affect my state of mind pretty awfully for the remainder of that game.
a) Wayfinder looks at top 4. b) you shouldn't make bad plays just to manipulate your psychology. if you're worried about your ability to properly process statistics, get better at that instead of purposefully playing poorly.
That's all very well, and I may be wrong, and if there were no other ways to get to a land in the block, I'd play the Wayfinder. But I will always play the Font over it. Again, this presumes I have a deck that actually benefits from playing a Font. Ours is not that kind of a deck, unless you count the small number of playables, which might force us to play a landcycler.
but Font wasn't in the pack. look, I'm not arguing we need to play the Wayfinder. we may not, although with our top end I do like mana consistency. but the point is, the existence of a bomb in our deck doesn't change that. not just that it's not a big deal, but that it's literally statistically irrelevant. the only thing wayfinder does in relation to affecting our chances of playing Ajani is reduce the number of games where we draw him but only have 4 lands. that's my point, and the numbers bear me out.
as for this pick, Head, Sands, Radiance, Hart.
