Does Kennen conquering, and giving Drag Under flow equal to its cost, let me play this for 3E and 1P

Question

Accepted Answer

Yes — assuming Kennen's conquer effect actually Adds Energy and Power into your Rune Pool equal to the spell’s cost, those added resources can be used to pay to play Drag Under. Because Drag Under is being played from somewhere other than your hand its Energy cost is reduced by 2 (5 → 3), so the total cost to pay is 3 Energy and 1 Power, and Added resources may be used to pay those costs [356.4.f] [357] [429.3].

If Kennen’s conquer effect Adds resources equal to Drag Under’s cost to your Rune Pool (or lets you Add those resources as a Reaction while paying costs), you may pay the card’s Total Cost (3 Energy and 1 Power when played from anywhere other than your hand) with those resources and play Drag Under for 3E and 1P.

Determine the Total Cost for Drag Under. Base Energy 5 and Power 1. Because you're playing it from anywhere other than your hand, apply its alternate cost text to reduce its Energy cost by 2 (5 → 3) [356]. If Kennen's conquer effect Adds resources equal to the spell's cost into your Rune Pool (or you can activate an Add Reaction at this time), those resources become available immediately and may be used to pay costs [429.2] [429.3]. Pay the card's costs using your Rune Pool resources (the combined Energy and Power amounts). Paying 3 Energy and 1 Power completes the Pay Costs step for Drag Under [357]. If all other payment/legality checks succeed, Drag Under becomes a finalized chain item and can resolve, performing its effect.

If Kennen's effect Adds resources based on the spell's original base cost vs. its discounted cost, timing/order matters. Discounts and base-cost modifications are applied when determining Total Cost [356]. If the Add is computed before you apply the discount, the resources Added might equal the undiscouted 5E/1P instead of 3E/1P, which still covers the cost but could be relevant for tracking how much was Added. If Kennen's effect is not an Add (for example it grants a discount rather than Adding resources), then you cannot treat that as resources to pay costs and the ruling changes [429.3] [356].

When you play a spell you must determine its Total Cost (apply base cost modifications and discounts) and then pay the combined Energy and Power costs [356] [357]. Drag Under has a base Energy cost of 5 and a Power cost of 1, and its text says it "costs :rb_energy_2: less to play from anywhere other than your hand," so when played from outside your hand its Energy cost is reduced by 2 to 3 (total cost = 3E and 1P) [356.4.f] [356].

If Kennen's conquer effect actually Adds Energy and Power into your Rune Pool equal to the spell's cost, that Add is an adding of resources. Adds finalize immediately and are available to be used to pay costs; additionally, activated Add abilities with the Reaction tag may be activated during the Pay Costs step and resolve immediately to provide resources for paying costs [429.2] [429.3] [357]. Therefore those Added resources can be used to pay the 3E and 1P required to play Drag Under.

Caveats: because you didn't provide Kennen's exact text, this ruling assumes the effect is an Add of resources (or an Add Reaction). If instead Kennen grants a discount, reduces costs in another way, or Adds only one type of resource (e.g., only Energy or only Power), the outcome may differ. Also be mindful of timing and whether the Add happens before you start playing the spell or as a Reaction during the Pay Costs step — either is fine for paying costs per the rules, but it matters for when you determine Total Cost and whether any other effects interact with that calculation [356] [429.3].
