Completing Missions Fast to unlock Characters/Progress Stages

In-game there are many stage or character unlock missions.

The bot can help you complete these fast via the PvE Duel Assessment, PvE Duel Assessment #2 and PvE Played Cards tab.

For example:
If you need to summon 60 Zombie type monsters, simply use the PvE Played Cards tab to spoof summon a Zombie type monster like Gozuki and set the amount to 60. When the duel ends, you will be credited accordingly:

Other missions like Perform 10 Tribute Summons can be completed by setting the tribute summons to minimum 10 and maximum 10 for example and clicking the Apply Preset Profile button:

Spoiler:

You have to be in a duel to do this.

Also be aware of safe practices when using the bot so you do not get banned. Doing 60 summons of a single card may not be a reasonable choice but it's allowed by the bot.

Please note:
All other missions or missions in general are common sense on how to complete them. If you do not know how some of the missions work, click on the mission text in-game to receive help. Furthermore, this is a good write-up on how certain duel bonuses and missions work. Only ask for help on how to complete certain missions if you really made sure you researched and thought about it.
