Notes & Combos

This is my KC Cup Deck. It only requires 1 copy of each of the Tachyon UR and SR cards from the Ark of Seventh Mini Box.

Out of 114 games, this deck had a 65% win-rate. The most prominent deck on ladder by far is the Tachyon mirror-match (18%), followed by Evil Twin (9%) and Branded (8%).

I was continually amazed at how this deck never lost to Evil Twin a single time no matter how hopeless the board seemed to look. Against Branded however, win-rate was only 1 in 3.

This deck really struggles against Princess Adena and Traptrix, the former I only beat twice and the latter I only beat once.

Spiral Galaxy is going to Limit 2 with Transmigration. So that second Spiral is going to have to be swapped with something else.

Tachyon Mirror Match

If your opponent has Harbinger turn 1, activate the skill on draw only if you have another spell for them to negate during the standby phase like Book of Eclipse. Otherwise it will be wasted.
