Switch Attack and Defense
Since having a good attack stat is usually more useful than a good defense stat, so you can use cards like Inverse Universe, Shield and Sword, and Ojama Country to switch these stats.
Use Spell Recycle: Field to return Field spells sent to the graveyard by Ancient Fairy Dragon's effect to gain LP back to your deck. An upgraded version of this skill is Field Restock which does almost the same as Spell Recycle: Field but this time it adds 1 Field card from your graveyard to hand and another Field card form graveyard to the deck. The downside is that you do not choose the Field spells to be added and you can only use Field Restock once per duel.
Field Restock Can be used when you have 3 or more Field Spell cards in the Graveyard. 1 random Field Spell in your Graveyard is added to your hand. Then, shuffle other Field Spells in your Graveyard into your Deck. This skill can only be used once per Duel.
