Playtest cards aren’t legal for play in any tournament format other than Mystery Booster Limited formats. On the other hand, we expect they will spice up a wide variety of non-tournament games (as long as everyone’s on the same page about using them!).
Playtest cards use a modified version of game symbols, such as {T} and {W}. These modified symbols should be treated as the standard symbols during play.
Value Town follows all of the normal rules of adventurer cards, except instead of casting it from exile while it’s “on an adventure,” you play it as you would normally play a land, following all normal restrictions. You can only play Value Town from exile if it’s “on an adventure,” it’s currently a time at which you could otherwise play a land, and you have a land play available.

For many playtest cards, you’ll need to make a generous assumption that basic game rules would be updated to allow them to work. The Mystery Booster 2 Playtest Card Notes section (reproduced here in individual Gatherer rulings) provides guidance for fitting these cards into the existing rules structure.
