Can a player tap 6 runes to float mana, then play and activate Singularity and Seal in the same turn?

Ruling: Yes, a player can tap runes to generate energy, then use that energy later in the same turn to play Singularity and Seal. Seal enters ready and can be activated the same turn it is played.

Sequence:

• Tap 6 runes to generate energy
• Energy stays in your rune pool
• Play Singularity using the floated energy
• Play Seal (enters ready)
• Activate Seal in the same turn

Nuances:

• Energy remains in your rune pool until the end of turn or the draw phase
