Keep in mind that you CANNOT protect this card with Equip Cards, as it will negate them, unless it's switched to Defense position. However, it can still get a boost from non-targeting effects such as "Molten Destruction" and "Limiter Removal".
A great way to boost this card's ATK is with "Rope of Life". Since "Rope of Life" targets a card in the Graveyard and not the field, it will give you a 2000-ATK beatstick, an insurance policy for your Machines and an extra draw should "Cyber Phoenix" be destroyed again.
Combine this cards destruction with "Defense Draw" for two cards and no damage.
