(what's it with forums these days and minimum amout of text in replies. Isn't yes sufficient anymore?? I really hate that)

[QUOTE=goblinguide]If I target Valakut Fireboar with Goblin Tunneler's effect then announce my Attack Phase and declare Valacut Fireboar as an attacker will it be unblockable even though its power and toughness switches?[/QUOTE]

Yes, because spells and abilities only check for target legality when they are cast/activated and when they resolve.

Once the Tunneler's ability has resolved, the Fireboar is unblockable until end of turn. <-period
