Unless a spell or ability allows you to, you can’t choose to pay more mana for a spell with a converge ability just to spend more colors of mana. Likewise, if a spell or ability reduces the amount of mana it costs you to cast a spell with converge, you can’t ignore that cost reduction in order to spend more colors of mana.
2015-08-25
The maximum number of colors of mana you can spend to cast a spell is five. Colorless is not a color. Note that the cost of a spell with converge may limit how many colors of mana you can spend.
2015-08-25
If there are any alternative or additional costs to cast a spell with a converge ability, the mana spent to pay those costs will count. For example, if an effect makes sorcery spells cost
more to cast, you could pay 
to cast Radiant Flames and deal 4 damage to each creature.2015-08-25
If a spell with a converge ability is copied, no mana was spent to cast the copy, so the number of colors of mana spent to cast the spell will be zero. The number of colors spent to cast the original spell is not copied.
2015-08-25
If you cast a spell with converge without spending any mana to cast it (perhaps because an effect allowed you to cast it without paying its mana cost), then the number of colors spent to cast it will be zero.
2015-08-25
Once you’ve gained control of a creature with Exert Influence, it doesn’t matter what happens to its power. Raising it won’t cause the control-changing effect to end.
2015-08-25
Check the creature’s power as Exert Influence resolves to see if it’s less than or equal to the number of colors spent to cast Exert Influence. If it’s greater, Exert Influence will finish resolving with no effect.
