3:42 titan player plays a mycosynth gardens as land for turn, then plays a bouncelands after. Also, spelunking only adds another replacement effect to lands that state "enters the battlefield tapped". in which case the player playing them chooses whether they enter tapped or untapped, otherwise it would be so much worse lol
Vesuva , entering at the same time as the radiant fountain, it is not legally allowed to choose the radiant fountain as a target/choice as the vesuva enters. The land must be on the battlefield prior to Vesuva entering in order to receive the enter the battlefield trigger, therefore the Titan player is only allowed the one radiant fountain trigger in game 1
