Ionize Discussion

The_Fallen_Duke on Makin' Your Wizz Burn

I would get rid of Lava Axe : never been a fan of spending 5 mana to deal 5 damage at sorcery speed. Actually I'd rather have 2 additional Shock instead (2 mana for 4 damage at instant speed), even though I believe that adding in 2 Ionize from your maybeboard as a replacement would be the best option, as they work both as counterspell and burn spell.

ArchonBlue I am glad that you are looking into Esper as your control build. I believe it is a criminally underplayed archetype. I would play Spell Queller since it's just a good card. I would definitely play one less Cryptic Command , as a three-color deck would depend on a very painful mana base to assemble that triple color commitment. Since you have specified an aggressive meta, I think that may be warranted.

Something I urge you to consider is that Jeskai Control is good because at the right time, it can function as a burn deck. The burn appears in Lightning Bolt , Lightning Helix , and the occasional Ionize . I think that you might be able to get away with running a really cool Esper Death's Shadow deck.

First, I think you should swap Search for Azcanta  Flip for Treasure Map  Flip. You'll still get to scry, and Treasure Map provides extra mana or card draw which is great for casting or triggering Niv. Second, Chemister's Insight is just too expensive. Try Chart a Course , Radical Idea , or Discovery / Dispersal in it's place. Third, Quench is fine for early game but Spell Pierce does just as much. I'd honestly drop both Quench and Sinister Sabotage for Ionize . Lastly, Cry of the Carnarium doesn't fit what you're doing. If I'm your opponent and I see you cast that, I'm immediately targeting your big fliers for removal to exile them. Run another Ritual of Soot instead since you have no creatures it would affect.

Let’s not forget that Ionize does, in fact, deal more damage than Undermine . Everything that triggers off life loss will trigger off either; anything that triggers odd damage will only trigger off Ionize .

Basically because of the deck they would be in coltron518. Izzet will deal a lot of damage quickly, and Ionize just helps with that. Odds are good that I won't be able to recover. While Undermine does technically deal more damage Dimir tends to be slower, this means that I can recover.

Basically the damage means little to me I guess (in a vacuum). What I'm more concerned about is the deck that these cards go in.

I think what I was more trying to get at was the situation the 2 cards are used in. In the case of facing dimir I would be more ok with looses the 3 life from Undermine . Dimir is more controlly so it doesn't do as much damage, whereas Izzet tends to do a lot of damage faster.

IDK, I guess it's more personal preference than anything else. I would honestly rather get hit by an Undermine than an Ionize (I think I'm just weird like that, lol).

DemonDragonJ: because Ionize deals 2 damage while Undermine does 3. one is a Counterspell with a Shock attached, the other is a Counterspell with a Lightning Bolt attached.

Darkshadow327, that is exactly what Undermine does, so I fail to see why Ionize is acceptable, but undermine is not.
