Deva will work just fine as an artificer as it has high Int and Wis.
An artificer can just live with Int. And IMHO controllers do need high attack modifier more than the other roles do. So I usually maximize the main stats of a controller (in case of Cleric, I usually go either Str 20 or Wis 20, never try to balance up two stats).
In case of Deva Artificer, after maximizing Int, you can go Con11/Wis14+2, Con13/Wis13+2, or even Con14/Wis11+2. Any of those stats will work fine IMHO. Even other builds can be fine. For example, you may want to have Dex13 for taking Dual Implement Spell Caster feat.
Many of the Artificer Power attacks single target. So Memory of a Thousand Lifetimes racial feature will work fine.
Artificer is a really customizable class. Which has both implement and Melee or Ranged Weapon powers. There will be so many good builds to make an artificer shine.
In the last sequel games, I made an human artificer who took Arcane Implement Proficiency (Swordmage/Heavy Blade) and Weapon Poficiency (Fullblade). And used Farbond Spellblade Fullblade as his implement/melee weapon/ranged weapon. One item works for every power (and in case of melee or ranged power, for both usage) was cost-effective. Thus he could spend more money on other items and ritual components.
And he could use all of his powers, melee, ranged close & area, without switching what he has in his hands. So he could always attack, regardless of his positioning. It prevented him from spending extra actions for movement. Also, his weapon powers were very effective (+3 proficiency bonus and 1d20 high crit).
