The rule reference states that Obstacles(including barrier, but not blocked spaces) can be targeted unless specified. So Gata can Free-run over obstacles. Then what happens if barrier is affected by displace effects? ex)'Fa Jing' from 8 Balls, or 'Be water Dude'. I think it is movable, though it'd surely not suffer any damage. and even the rule on 'Effects' says obstacles are valid targets for any effect unless otherwise stated. I hope some official answer is coming. thanks for the great game.
